Just figured with that high of a RPM range every so often the RR would need adjusting (like solids). The "go or blow" is just an old saying on the back road "drag stipps" of south fl. It's either gonna make it or it's not hence "go or blow".Redsnk95 said:Not sure what the "go or blow" statement means. This is all motor and it is pretty bullet proof. As for the rockers I adjusted them once after some initial heat cycles and haven't touched them since. You shouldn't have to continously readjust stud mount rockers on a hydraulic roller, I shouldn't have to touch them at all.
