prc 237 heads are prob too big for what you need.
but i need more details man. what headers, what exhaust, cats/no cats, what tranny, what kind of stall, was the converter unlocked on the dyno etc etc. sorry but i don't know these truck inside and out. also keep in mind the point of a stroker is to make good mid range torque numbers. and i've heard VERY mixed reviews on the pro flo intake. i maybe would've gone with a FAST or a single plane.
