Ok.....;.. I have built a grand total of 4 sbc's. Each of which have had relatively the same problems. I have finally gotten an aluminum intake to seal. Whoo hoo!! I still seem to have a hard time with the oil pan. But im going to try to use one of felpros one pc gaskets. Btw.... all of the engines have been pre 86 blocks. Anyway......the one problem that i always have is that after running the engine on a stand for a while after breakin, i seem to get oil on the plugs. I havent gotten this engine in the car yet to drive it. Is it possible that all i need to do is get some street time on it? Like maybe an engine running on a stand wont allow the rings to fully seat? I have been messing with this thing for 3 weeks on the stand. Is it also possible that the rings will never seat right now due to running on my stand?? I really thought I had the answer to my problems by finally getting the intake to seal.... PLEASE help
