COMP Cams offers a complete line of valve seals, from the stock GM O rings to the positive-stop PTFE seals. They are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O ring seals use the standard retainer and oil splash shield. The umbrella seals are normally used when a larger than stock diameter spring is used. In the case of a double spring, the positive stop PTFE seals are used. For triple-spring applications, use the smaller-diameter Viton seals.
