Cylinder Head Poll
I'm just trying to get some ideas on what to buy when I have the money. If it makes a difference I already have a GT-40 intake, 24lb. injectors, 1.6 fms roller rockers (not that I have to stay with the pedestal mount). Lets see what everyone has.
1) Brand of Head/model 2) best E.T./M.P.H. 3) Where did you get them/Price 4) If you had to do it all over again, would you get the same ones or something else (Brand/Model). The car will probably be 90% street driven until I buy another one. Any replies would be appreciated. ------------------ 1989 lx notch 89,000 miles bolt-ons,stock heads/cam 60'- 2.07, 8.90@78, 13.93@99 |
1. Cast iron GT-40's
2. In the sig, stock intake and cam 3. Off line, $400 4. Yes, but I would have them ported, with bigger vavles. ------------------ 87 GT, 4 inch cowl hood,17x9 Cobra R's/255/45's,GT-40 heads,long tubes headers,h-pipe,Flows,BBK cold air, Mass air,70mm MAF, 1.7's, 1" spacer,underdrive pulleys,Pro 5.0, King Cobra, Adj. fuel Reg., Lakewood Lift Bars,50/50's,subframes, 4.10's. Best time 12.96 Best MPH 103.42 Best 60' 1.695 Visit my site at: http://www.geocities.com/cobrar93_2000/MyPage.html |
from what ive seen the victor jr heads are the best heads but it would be better to get a set that matches your intake so if i was you id go with the gt40 heads
------------------ 1995 gt convertible: 3.55 gears, underdrive pulleys, cobra intake , fenderwell cold air, 65mm throttle body, 75mm mass air meter, off-road h pipe, borla cat back, custom diablo chip, 155lph fuel pump lentech aode street terminator w/ 10" converter stalls at 2800 rpms, yokohama a520(drag radials) 275s |
GT-40P's - about $700 complete from Central Coast Mustang. They require P-specific headers though. I haven't run it, but I dyno'd 277 RWHP.

Thanks for the replies....I don't mind the GT-40s or GT-40Ps, I think they make good affordable power. As of now, I'm leaning towards the Trick Flows. Anyways, lets keep the responses coming.

I went with Trick Flows and I would do it again. I got them from Summit. Never been to a track, so I can't tell you. When I get the courage, I plan to go to a local dyno. I'll post those numbers when I do.

I haven't bought them yet, but as for flow numbers, the AFRs can't be beat. Comparing the street legal heads, anyhoo. I found it interesting their 1.94/1.60 valved head outflowed others with 2.02/1.60 valves. Must be something with that CNC-made ports and chamber. I think it was sedanman that talked with some dude that had an 11 second LX that ran AFRs. Check out their site here to learn more. Those heads look so nice, all made from aluminuminuminuminum....hehehehe. http://www.mustangworks.com/msgboard/biggrin.gif
Oh, with those 24lb/hr injectors, did you get a matched MAF sensor??? BTW, I'm getting a Cobra intake, 65mm TB, E303 (possibly a Novi2000), and I already have BBK full lengths, H-pipe, 24lb/hr juicers, and a 77mm ProFlo MAF. Hope this helps. ------------------ Capri306, Moderator, The Mustang Works Online 1979 Mercury Capri, 5.0L -- C4 -- 2.73 1987 Mustang LX Notch |

edelbrock 6022`s

I chose the canfields and would never get another head. I did allot of research before buying, and a most of the people I talked to also agreed that the canfields are exellent. I also paid the big price that comes with them. 1700.00 stage 2 bare except the valves (ouch). I assembled them my self with better springs, locks, and retainers that they offered for less $.
------------------ 347 W/ A-trim 6#'s, Canfield heads, out of the box Systemax II intake, solid roller cam. 11.1 @123mph 93lx 5.0 daily driver |
I like my plain old common edelbrok 6032's. (ex. ported)and I have the small valves too. Velicity builds torque. Don't go too big with a street car. I think I might try the victor jr's next. You cann't go wrong with Edelbrok on it. Best time 10.13@135 mph

Capri...I am running a Pro-M Bullet calibrated for the 24lb. injectors. In cold weather the car used to die right away after the initial start-up. Also, it would have a bad idle surge when sitting at a stoplight. I think I remember seeing other topics about this before on this site (something to do with the fuel curve of the 24s being different than 19s). Anyways, one day I reset the TPS (.98v) and adjusted my idle (600-700 on factory tach) and haven't had a problem since. Now it idles perfect and never dies after I start it up in the morning.
WADS56...Do the Canfields have raised exhaust ports and require special headers? They're supposed to be developing some new small block ford head aimed at the street cars. 5.0 had an article about them. I called Canfield up awhile back and they said they were having problems with the coolant passages so the new heads weren't out yet. Thanks to everyone else that has replied. Looks like a lot of strong running cars out there. ------------------ 1989 lx notch 89,000 miles bolt-ons,stock heads/cam 60'- 2.07, 8.90@78, 13.93@99 |

1. Edelbrock RPM (version w/ the thermactor

I'm in the process of 'upgrading' again to a street/strip combo with the emphasis on strip. I'd go with victor jr's or AFR's now but I'd also run more cubes. The Edelbrocks were quality all the way. |

I also have the canfield heads and yes I would get them again if I were in the market for some heads again.
MM&FF had an article on a lot of heads in one of the issues and they said that the canfields made about the same torque but made 8 more hp than the tfs heads. I have been told the canfields are too big for the 302 and are better suited for a bigger motor or forced induction but they still work well on the 302. I have ran a best of a 12.5 @109. And that was with the wrong fuel system (EFI fuel pump and fuel lines with a carbed setup) and A bad syncro in third gear; and I do not power shift because of the stock t-5). I got them at excessive Fuckups... I mean motorsports. I would not get them from those people. The fuel system is in and I have installed a NOS system so I will get some better #'s soon. I hope to be close to 11's on motor. If I had to get a head other than canfield I would go with AFR. ------------------ James Cox nochevy@hotmail.com 1991 Mustang LX 12.565 @109.38mph 1.764 60ft |
I think the TFS, or AFR's are the way to go, the intake 1ports on the canfields are pretty big, (19* cc if I remeber right), WADS56 seems to be doing good with them, but they're on a blown 347, so.... I'll probably get TFS Track Heats, juts 'cause they're cheap and I'm in High School....

I've thought about the AFRs, but I don't know if there worth $1400. There seems to be some good times coming from the corral with those heads, but most of those guys have custom cams and lightly ported (gasket matched maybe) intakes.
What do you guys think of the Brodix ST 5.0 heads? Awile back 5.0 got 20 - 25 rwhp out of an otherwise stock mustang. With intake and exhaust (along with the little stuff), I don't think 40 rwhp would be out of the question. Plus you wouldn't have to buy new rockers or pushrods. On another note...With aftermarket heads, which valve would be closer to coming in contact with the stock piston with an aftermarket cam? For example, with a 1.90 - 2.02 intake and 1.60 exhaust valve which one would be more likely to hit as far as p/v clearance goes with a single pattern cam?

AFR 165 or 185 cc (intake)/70 cc (exhaust) TFS 170 cc (intake)/66 cc (exhaust) Flow ratings @ 28 inches of water: Canfield 258 cfm (intake)/195 cfm (exhaust) @.500 lift AFR 165 250 cfm (intake)/191 cfm (exhaust) @.600 lift AFR 185 282 cfm (intake)/191 cfm (exhaust) @.600 lift TFS 251 cfm (intake)/193 cfm (exhaust) @.600 lift I do not know why the canfields are rated at .500 lift but I talked to Bennett Racing and they told me that the stage 1 canfield heads flow 278 cfm (intake)/208 cfm (exhaust) @.600 lift. The canfield heads are probably a little too large for a natural aspirated 302 unless you are going to turn 7500 to 8000 rpm's.

BTW: The reason I went with canfields is because they do a little better that the TFS heads on the 302 but there is more room for improvment if I ever go with a blower or more cubic inches.

I went with iron Windsor Jr heads cause I could not afford aluminum. Im happy with the results. I had them cleaned up. I am running everything except smog pump.
1. Windsor Jr Iron Heads 2. $798.00 @ Holcomb Motorsports delivered. With the clean up total was under $1000. 3. 12.91 @ 105.4 mph 1.71/60ft 5-11-01 4. I would buy them again if I had to.

grey92lx...Did you upgrade the valvesprings on those windsor heads? I've heard/read that the stock ones are pretty cheap, is there any truth to that? I helped a guy put a set of Windsor Sr. (2.02/1.60 valves) on his car. It was a 89 or 90 GT vert with a 5-speed, stock shortblock, E-303, GT-40 intake, 3:73, etc... Anyways, he bought them bare and had upgraded hardware installed by a speed shop. The car felt really strong and pulled hard through the first 3 gears. It seemed pretty scary when riding shotgun in it.

I talked to a guy at Canfield today for about 30 - 40 minutes. He said that the new 18 degree (street fighters) should be out in a couple of months. I believe they have a 165cc intake port volume. Anyways, he thinks my car would do really well with their current small block Ford head (2.02, 160 valves), milled to 54cc chambers (compression about 9.9-1), and stock cam with 1.7 roller rockers (he said there should be plenty of p/v clearance). The intake port volume is 192cc, which was mentioned by FiveO. Also, my current exhaust (1 5/8 shorties & o/r H) would work for now, but recommended 1 3/4 longtube headers. He said I'd lose a little lowend torque below 2500 rpms, but gain a lot in top end. A customer car is in the mid-elevens with a similar set-up (stock shortblock, cam, & 1.7s) while shifting below the stock rev-limiter. I know you guys think the heads are a bit much for a 302, but could the combination work that well?
He also said that if I decided against buying one of their heads, to go with the WP Windsor Srs. bare and have good hardware installed. Overall, he seemed to be very knowledgable. The current heads are about $1400 fully assembled. ------------------ 1989 lx notch 89,000 miles bolt-ons,stock heads/cam 60'- 2.07, 8.90@78, 13.93@99 [This message has been edited by TJR (edited 05-18-2001).] |
Edelbrock 6037's Bolted right on no problems plenty of low and midrange power nice clean to 6000 rpm pull awesome head. Blew a haed gasket from my own stupidity cke'd the head out it was mint. Needed no milling no nothing. The edelbrocks rock!

CANFIELDS!!!!
------------------ 91LX 306 S-Trim & 89GT NOS Stage II |
I would go with the canfields.
You will lose a little low-end torque but will pick it back up high in the rpm's. That will help you get better traction because you wont be so likely to spin the tires so bad out of the hole. And if you ever get more cubic inches or a blower or NOS, these heads really perform. ------------------ James Cox nochevy@hotmail.com 1991 Mustang LX 12.565 @109.38mph 1.764 60ft |
