Camshaft/Valve clearance question I have installed a bunch of cams that produced 560-580" valve lift with zero valve clearance issues. I recently picked up an unidentified cam that will produce a .612" lift.
Is there a general rule of thumb about lift and clearance. Simply stated - you don't typically have valve clearance issues until XXX lift. I understand it depends on duration and other cam specification. I am asking a for a general rule of thumb answer.
My goal is to toss it into an engine with valve springs and run it. I am hoping to avoid pulling heads and clearancing work.

What heads? Lots of variables here. Duration plays a larger role than lift does. Springs must be set up for the camshaft. Pushrod length prolly won’t be right either. Your asking for trouble in my opinion, to just throw a combination together and go.
