As previously stated, oil leaking form sbc head gasket is very rare, only a drain back to pan is used in the sbc head, no oil pressure feed through head gasket is used. most likely culprit is intake or valve cover gaskets, Intake end seal will follow head gasket to back exhaust port. Use a mirror to inspect after cleaning and running at some rpm to verify.

Well we fired it up on friday afternoon and cleaned the whole area where the oil was leaking. Apparently it is leaking from a pressure tap type plug halfway under the head surface. I looked at another block and its a 1/4 inch square plug, similar to the one on our motors by the distributor. Its not a really bad leak, so we cleaned it again with brakleen and filled it in with rtv. Not a permanent fix but at least it will drive into the garage instead of pushing it. Now we'll just have to find some time to take the head off. Thanks again!
