Anyone else tried this yet? I had very good results when I did it years ago. I just ported the exhaust side, out to the diameter of the exhaust gasket holes, and blended it in towards the combustion chamber. Also got the pressed in rocker studs removed, and put in screw in studs. You have to mill the pedestals down a bit and drill and tap the holes, but it was worth the price. With a set of roller tipped rockers you have a mean set of heads fairly cheap. If you have extra cash, consider larger vales too.
I got the info years ago from HotRod or CarCraft magazine. They did an article about it. :hy:
