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 have about 20k of the hardest miles hitting 6k rpm's 4-5 times per drive on them.

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?

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. I would also buy some AFR If I could afford them. ------------------ 92'LX Notchback, BBK Fenderwall Cold Air EDELBROCK Per.

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.
Does anyone know what the difference is between the new Roush heads and the old world product heads? ------------------ 1989 lx notch 89,000 miles bolt-ons,stock heads/cam 60'- 2.07, 8.90@78, 13.93@99 |
Im using the 1.250" springs it came with (assembled) Ive had no problems Im using the f cam .512 lift not to much to handle for the 1.250" springs. I to have heard about the springs failing. Not sure on the new Rousch heads.

fastang...When I buy a new set of heads, I'll probably go with stud mount rockers. I hate messing with the shims when setting the preload with pedestal mounts. Then I'll have to get hardened pushrods since stud mount usually have guideplates.
Where can you order the AFR 165s without waiting at least a month to get them, does anyone know? ------------------ 1989 lx notch 89,000 miles bolt-ons,stock heads/cam 60'- 2.07, 8.90@78, 13.93@99 |
I got mine direct from afr inside of three weeks, and that was after they put different springs and valves in.

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!!!!

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 |
