Guide with an OD of .625in. Set of 16. Requires machining the top of the valve guide with a special .500 in. diameter cutter.OMP 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.\u003c\/p\u003e","brand":"Pro Parts NZ","offers":[{"title":"Default Title","offer_id":46014106140845,"sku":"COM515-16","price":6.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/4819\/4989\/files\/COM514-16_11a3a0ef-4c20-4fea-98f5-ffe7b5310152.jpg?v=1778849295","url":"https:\/\/proparts.co.nz\/products\/valve-stem-seal-3-8-530-viton-each","provider":"Pro Parts NZ","version":"1.0","type":"link"}
