Providing the best sealing properties and spring clearance, viton valve seals are an excellent choice in performance applications. The 511 seals have a .600" OD and fit LS applications with 8mm valves and .500" OD guides.
Comp Cams(R) offers a complete line of valve stem oil seals, from the stock GM o-ring to the positive-stop PTFE seal. These seals are a must to keep unwanted oil form 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 seal is normally used when a larger than stock diameter spring is used, and in the case of a double spring, the positive-stop PTFE seal is used. Small diameter Viton seals are also available for triple spring applications.
