I know these are not the best heads to get high HP out of but as my budget will allow me to do this is all I have to work with. I have read and read write ups on DYI porting and hopefully learned what to do and what not to do. Any input will be appriated as I am a rookie.
1st mistake I made on the first attempt was I wore through the pushrod pinch point, I got greedy and careless and paid the price lol
On the second attempt I proceeded to Blend the bowl, remove any casting marks and just smooth out any areas that air can flow
pic here is the intake bowl and runner




I have felpro 1262 intake gaskets(am running a trick flow street heat intake) are these gaskets Too big? I was going to curve the intake port and not completely gasket match it. does that sound right.
on the exhaust port I blended the bowl smoothed any crappy casting and opened up the exhaust port a little bit




any tips or am I doing this completely wrong. I have a set of 100% stock E7's on my car now and am not expecting drastic changes but I do expect a bit better preformance

Wow, pretty impressive. I don't think I trust my skills enough to tackle a porting job like that. Way to go! Let us know how it all works out for ya.

I def will, I will post updates along with pics. They will be flow bench tested when they are finished

Very nice. I ported a few years ago, and they came out good, and seem to work really well.

I didn't change the runner size as I read and was told that can hurt flow. I really opened up the bowl and did a lot of smoothing in the bowl. The castings are terribly crappy lol

Well 16 hours later I finished up the head. Opened up and blended the bowls, smoothed the intake and exhaust runners and opened up the pushrod pinch areas on all intake ports. Its incredable how much casting crap was in there. I will have pics of the finished product tomorrow.

Here are some pics of finished head

And more

I never did a dyno test before but the car ran a best of 12.8 @ 104 mph NA.
Hopefully the work I have done will help the car gain a couple of 10ths and a few MPH

Those look really good!!

Thanks, I got a assortment of hard stones to smooth the grinding marks and got some valve lapping paste to re seal up all the valves
