Valve Stem Seals

Valve stem seals are for full size aftermarket guides and requires matching. These seals have an outer diameter of .500". Accepts valve stems with a 5/16" diameter and a .415" outer diameter valve guide. Check the valve to valve clearance when installing any performance camshaft that may affect the lift and duration of the valve. We recommend a minimum for the closest point of contact is .060".
