    Are you sure it is the head gasket, and not the valve cover gasket?

      Sounds like a valve cover gasket to me!

        It could be the head gasket. There is a oil passage from the block through the head, in that area, but need to check and make sure. VC gasket is much easier.

        O.P. has to absolutely find the exact source - like when dripping from bottom of bell-housing and blaming rear seal - - when in fact it turns out to be way up at the VC gasket. Oil moves down almost invisibly - until you wipe area and notice residue. Just be sure of exact source - no ifs, ands or buts. Could save lots of wasted labor time and parts costs. Please post back - thanks.

        78 didn't have the tubes. Head gasket finally went. so gasket was replaced!

          well changed the head gasket ,it was already a composite one. so someone was already there.
          lasted about 3 days and this time it really puked it. antifreeze coming through the carb.
          time for new motor!
