These seals 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. \u003cdiv\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003eValve Stem Diameter: 0.344 in. \u003cdiv\u003e Valve Stem Seal Type: Positive stop \u003c\/div\u003e\n\u003cdiv\u003e Valve Stem Seal Material: Viton® \u003c\/div\u003e\n\u003cdiv\u003e Machine Work Required: No \u003c\/div\u003e\n\u003cdiv\u003e Valve Guide Diameter (in): 0.500 in. \u003c\/div\u003e\n\u003cdiv\u003e Valve Stem Seal Outside Diameter (in): 0.546 in. \u003c\/div\u003e\n\u003cdiv\u003e Quantity: Sold as a set of 16. \u003c\/div\u003e Notes: Designed for triple spring.
