PRC 237cc Heads Looking for people running the PRC 237 heads and their results and combos.
Did a lot of searching, but a lot of the threads are older and still very little info to be found.
So having said that these will be going on a 408 stroker
Also, if TSP chimes in what would the PRC 237 heads cost WITHOUT valvesprings?

Also I hope with a lot more cubes (408) im hoping for 500/500+
I'd like to think here that ive got a very well rounded thought out setup and should be capable of doing more than my goal, or at least I sure hope so!
