I am going to have the sump off and check main and big end brgs. Also piston clearance.
Can't do it for a while yet, I will post what I find here when I do it.

Block was ultimately stripped, at that time it was found that the cam bearings were installed previously backwards. Combined with a narrower than normal hole on the head gasket, there was not enough oil pressure to get to the head.

So issue is/was oil pressure, either from pump or from internal leaks from bearings - mains, bigs or cam.

Motors back in a vehicle now after full rebuild and purrs along fine.
