I'm positive it is the head gasket leaking unfortunately, as the leak was still present after replacing all the cam gaskets/seals/o-rings years ago (that was the highest point on the engine that oil was leaking from, right near the LF corner of the block where the oil passage is). Aside from making a bit of a mess, that was the only issue with the head gasket, no intermix of fluids and no compression leakage. I left it alone since I had just slapped fresh parts on the engine all around. Kept an eye on it and it didn't get any worse. The passenger side has developed a slight wetness in the opposite corner (RR) where THAT head has it's oil feed, with nothing farther up the engine leaking.
