COMP Cams Valve Seals
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.

Awesome and Invaluable Reference
Format: Paperback
I purchased the 2nd Edition Reprint in 2023. As a former US Army Special Operations Critical Care Flight Medic (160th SOAR Nightstalker) and current Remote Critical Care Flight Paramedic, I can honestly say this handbook is leaps and bounds above some of the other handbooks I've owned.
I never leave home and go to work witout it.
