Product Description
Comp Cams Valve Seals: Positive Stop Teflon, .530 Guide, 5/16

These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. In the case of a double spring, the positive-stop Teflon seal is used. With the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don't forget the valve seals.
