hey, i was lookin into some regrinds, im getting the ZE with 03 valvetrain etc... so i went to colt cams and they said the best they can do is .355 lift and 210 duration, for $440. I know the ze is .350 so is it worth it? Prolly not, thanks
P.S. wat is the valvetrain tolerence for the 03 springs and retainers? .400 lift?
