Product details
MECHANICAL ROLLER-Perfect for mild modifications, optimized fuel mileage and improved torque/hp. Good for heavy towing.
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.
