Who has done home porting on iron gt-40 heads?

  • Sponsors (?)


I bought a set of those heads fully ported and polished by a machine shop. I was very happy with the gain over the stockers. Gained about 25hp. Only disadvantage is that I still want an aluminum head for better flow and the advantage of less weight. So Im gonna have to go though swapping heads again. Not my favorite thing to do.

Funny I have always heard that if you had a iron head and an alum. head that were equal in flow/portsize (identicle(sp?) I mean) that the iron head would make more power and the alum. would just be lighter. So are you saying you want some higher flowing heads, or that you feel if your heads were alum. they would flow better?
