So you don't support roller lifters in stock? My apology if thats the case, but It does appear you have success without having to run roller cams and lifters.
What I dont understand is why are some having success without running tool steel coated lifters and some not. Does it have to do with the inferior cams or lifters not being able to tolerate lifters bores not aligned correctly?
Is the movement to go to roller lifters and billet cams to try to save cost? If so, why isn't there a movement to go to stock ring width? You could almost buy a a set of billet cam and lifters for what some have into ring packages with spacers. Evolution has put us in this situation, and it appears there is no going back. But for every new rule change, such as a roller lifter change, it would bring in a cost that those with money would excel, and those without would be farther behind the gap.
