I was browsing through the sdpc catalog today, and was wondering if any of you guys has tryed the gm performance parts small block tbi heads. there 1.94/1.5 valves and 64cc. not badly priced, so with the mods listed in my sig, what could i expect with these?

64cc is too big for a 305, 58cc is ideal i think. The bigger you go, the more compression you will lose, and that is bad. Those are better suited for a 350
