Porting stock heads - Page 2

88workcar · 05-18-2005, 08:43 PM

I am so glad to see you take on such a project. I did the same 8 years ago and I still learn suff about it all the time. The reward for porting your own is wonderful. I did a set of stockers last week, I will try to send you some pics. The first set I did was good for .3 tenths, then the next set was good for .5 tenths and 4mph. I did a set of camel heads and the guy spun about half track and blew the bottom end to hell(stupid chevy man) then came back bragging that it was because of the added power. GO FOR IT, you will be happy

Between the good air where you live and your light car the results you are able to achieve are unattainable for most of us.

I can't say one way or another if it is worth it or not to port stock heads. Not much to lose though. Anyway, I had to clear up the "adjustable T" gauge part. If you are referring to what I think you are, that is called a telescoping gauge.

I know that what you do to them right now will not Gain the results that I will tell right now. Do yall remeber when MM&FF did the test on POWER HEADS. JUST a head change was good for 42 HP if I remeber correct, JUST THE HEADS. Throw in a cobra and an E or B cam and an easy 50 to 70hp gain for the whole project( on the high side) But the thrill of doing it yourself is priceless

rwhite65 · 05-19-2005, 10:35 PM

I gotta agree, Doing it yourself gives you a since of satisfaction. Always a good starting point too.

Power heads have bigger valves and are cnc ported. Wish i had a cnc machine in the garage.

When I went from being stock to installing an explorer intake, ported heads and 1.7RR I went from a 14.46 to a 13.66 and from 96mph to 102mph.

Interesting thread, but are all stock heads worth the time to port, I heard that the E5 and E6 heads are boat anchors, is this true?

83GTMUSTANG · 05-20-2005, 07:17 AM

these HEADS HAVE A SMALLER COMBUSTION CHAMBER (HIGHER COMPRESSION RATIO)THEY WOULD BE GOOD CANIDATES FOR A PORT JOB...............

I am not sure about E5's but E6's are junk.

rwhite65 · 05-20-2005, 08:40 AM

He has been talking about the e7's, unless I am mistaken. The e7's respond well to porting.

Update...The engine turned out to be an 86 Lincoln engine...

I'm an idiot for not running the casting numbers on the block...I'm going to go ahead and assume that these heads are completly and utterly useless? Looks like I'll be shelling out the 1700 for a good set of AFRs.

rwhite65 · 05-27-2005, 01:18 PM

If you were going to be porting stock heads, the e7's would definately be better.

The heads are the best place to start. Stock heads can be ported to gain an HONEST 25-30 HP with a good valve job. It is a job for a professional or someone very experienced with a die grinder(a Dremel tool WILL NOT get the job done). A good set of heads with a weak cam will outperform a hot cam with weak heads every day. It depends on your budget & goals between iron or aluminum. I just did a set of GT40 heads picked up 21cfm on intake, 12cfm on exhaust! I am in No. VA if you are interested.

Well, I decided that due to the heads not even being decent heads on the engine, I'm going to cop out and buy a set of AFR 185s. They come CNC'd, so I won't have them ported professionally even, but they should slow nicely. Maybe down the road I'll buy a few tools and practice a little - maybe I'll just practice on these shitter heads I have just to see what I can do, but I'll just stay with my 302 and build it up with good heads.

skiwesser · 06-03-2005, 01:48 AM

I've only went to track once since I ported my intake & heads and had them milled, added 1.7's, valve job & springs, 65mm TB.
went from best of like 8.89@78.3mph to 8.75@78.9mph 60ft stayed same 1.86-.190 range, again I've only been back once since mods (both in cold weather 11/03 11/04)
Hope to get back soon! With NITROUS!! ON A 150,000mi. short block!!!!!!

NOTCH306 · 06-07-2005, 05:50 PM

my buddy just starting porting my factory heads the e7's i'll get you guys the stock flow numbers tomorrow and then follow up with teh after numbers.

Vip18971 · 06-08-2005, 02:32 PM

Sounds good, I look forward to hearing the results.

If they respond that well to porting, I might have to find somebody's junk E7s and port them myself, since the price of AFR heads could really be put to good use in beefing up other parts of the engine.

I guess at least I have a set of heads to practice on with these 86 Town Car heads...?
