World products heads

need at least a 64cc chamber but i was wondering about the SR's with the 1.437 springs any problems and has everyone that run them happy with their results.........this decision is about to unfold for me to choose my cam profile.
the engine is a flat tappet stroked to 372 with CR @10.4:1 w/64cc chambers.

Re: World products heads

I'm running a set on my 393, car went [email protected] granny shifting with a mild cam and dual plane.

As cast there are better heads available, however when properly ported these heads can make good power . Plenty of users well into the 10's after porting.

I'm selling this engine and building a slightly larger version this winter.
