Randy, thanks for the interesting read. I let my builder put the 88cc eddys on my 451 low deck w/ the 440 source stroker kit & am worried about having no quench. He says its zero deck, but I'm tempted to mill the heads. I've read that CNC ported stealths flow pretty well, but would the small chamber eddys w/ CNC porting be better for his 500 build? Would the Max Wedge exhaust limit the power?
