COMP Cams® always recommends checking piston to valve clearance whenever installing a camshaft. Modern engine design dictates a compact combustion chamber and tight clearances. Tolerance stack or installation errors can result in interference and failure. COMP® recommends .080" intake and .120" exhaust minimum piston to valve clearance in most applications.
