Here are some pics of the GT40 (not "P") heads that I have been working on. What do you guys think of the progress? Is there anything that you can see that I am missing? The tapered areas below the valve are actually a lot more rounded than they look. Very tapered and smooth. I have really only opened up the bowls on the exhausts and really haven't done more than taper the valve bosses on the intakes. Should I hog out the ports, themselves? Or just match them to the gasket, as I have done? I've done the best I can to smooth the transition from a round valve to a square port. Opinions?
I remember a post a while back from someone who said that they would like to port heads on a fee basis. To be honest, I couldn't CHARGE enough to make it worth it to me. I have about 25, or so, hours in what you see. (Of course, I'm just using a Black and Decker hand drill with carbide burs to cut the iron.) I enjoy doing this kind of stuff for myself, though. Very rewarding.
PS--These heads are from an Explorer. How much needs to planed from the head to yield about 9.5/1 compression ratio on a stock 94 GT block?
