    Are there valve stem seals on a stock f-head ? I see what looks like umbrella type intake valve seals on the engine I am working on. I thought they only had o-ring type seals. Are these umbrella seals aftermarket ? IF so, any idea what part number to replace them ?

    ALSO, are there valve stem seals on the exhaust valves ?

    I'm getting a huge amount of smoke and oil blowing out the exhaust. I know I might have ring issues and/or valve GUIDE problems, but I'm trying to at least reduce the oil/smoke on the cheap - just so I can get it running without fogging the neighborhood.

    Compression is 115 per cylinder, so I'm thinking at least the compression rings are ok.

    Any help would be appreciated.
