which head??

Subject: which head??
by grant76 on 2010/6/1 4:54:01

Aiming for a nice street engine with 90-95hp. I have an a15 with h89 head, a gx head with carbs and exhaust maniflod, and another set of gx carbs. I haven't had a lot to do with the gx stuff, but just wanted opinions on which would be the better option
1. porting a15 head to match gx manifold or
2. using gx head on a15
I know the gx ports are slightly bigger but the valves are smaller?? any help would be appreciated
