    the yellow z06 springs are just fine for cams under .570 lift...how many have you actually heard of failing?

    Whos said I was going under .570 of lift? I dont know what cam yet, now I can get whatever I want and not have to worry. Only takes one to take out a piston, valve, head, cylinder.

    I have never heard of Z06 springs failing--even when they are used on .590 - .600 lift cams. Yes, its true--there are some people out there who have done this and gotten away with it...for now. When you take a mechanical part and push it past its recommended operating range, it can hold up to a point...but eventually it will fail.
