Thanks !
That was great info. I didn not know that !

ok..... my appears my heads have NOT been worker over before hand then. all oem then.
When I installed the new valve stem seals, the old seals were all in pieces !
it was smoking like a locomotive ! now with the new seals , it's better but when you get on it hard it still smoking . must be another issue .
