Looking to replace my black rubber positive intake valve stem seals. Engine is 427, valves are 3/8" stem, guides are NOT cut down (.625"). I can't find the right part # for non-cut down guides. Anybody know the #?
this guy? https://www.ebay.com/itm/Sealed-Powe...ZaAjEn&vxp=mtr fits .625 guide. .792 od. just barely fits inside some double springs. goes good inside singles and beehives. i trim the top of guide about .050 so .540 cams have enough room to spare. i dont run them on the exhaust. or any seal.
