Ran into the same problem a few years back, The machine shop pulled the plugs from the oil galleries, front of the engine behind the Cam gear, There are 3 5/16 frost plugs or tapped holes. The machine shop did not install and in my rush to put the engine in I did notreplace with new plugs Had reasonable oil pressure when it was cold, however it dropped fast.
Chewed the crank, hope you find your problem befor that happens
