Default Porting Dart heads??
From sifting around the theads i can find, it seems that to get a gain from my Dart 225 as cast heads, the main thing to do is take out some metal from around the valve guide? I am going up to a 4.070 bore so would anyone say any combustion chamber work could be beneficial? Anyone with any actual experience done anything? Cheers.

Check with Texas Speed. I would avoid trying to port the dart heads.

Darts respond very well to porting. I would give Bret Bauer or Ed Curtis at Flow Tech Induction a call.

I agree. Bret has done some pretty good things with these heads and works with them a lot.
