Thanks Paul for encouraging note on retoque. My head has not been re-torqued, shop just indicated on similar problems they had had little success. It is external leak, right front corner and rear of head. Normal oil pressure on this engine is 70 to 75 psi whereas many engines run 40 to 45 which is part of the problem, I suspect. Ford 351 cleveland engine ran 70 to 75 psi oil pressure as it too was built to tight tolerances but it had heavy heavy cast iron heads.

I will also do search.
