I think I may go with these heads

RHS Cast Iron Vortec The summit ad says they have ductile valve guides, but RHS's site says they're bronze.

It will get an edelbrock 2716 EPS vortec intake.

Still sticking with the XR264HR Roller Cam

I want my comp ration between 9:1 - 9.5:1 somewhere in there is fine.

The truck will have headers and 2.5 dual exhaust, and h or x pipe. cherry bomb vortex mufflers.

Anybody have any bad things to say about the RHS heads? I don't hear of them a lot, but I've only come across good things.

Anybody ever heard this cam? Comp XR264HR Roller.
