This is beyond frustration. I had a shop West of Cleveland who claimed to be highly experienced in this engine. I couldn't find anyone local to do the work and any of the suggested shops were much further away plus that 440 shop in the Detroit area only does the work unless they do a hundred percent rebuild.
So here's my tale: I have a a nine year history on Mopars in the seventies so I'm hardly a shade tree mechanic. This engine is out of a motor home and I went through it completely. Once I replaced the worn parts, new old stock oil pump, checked the pressure valve operation and it performed as designed. I was pretty sure she would be ready to go. However before I put it in the car I used that oil pump drive shaft tool and a hand drill to see how the oiling would work. It didn't, only a trickle came from number four two lifters? I pulled the heads and the oil galley from the block to heads where dry. I tore the engine down and found no oil was getting through due to the cam bearing associated with the block oil passages block due to miss installed bearings. Drilled both sides out, reassembled the engine. Again using the oil pump drive I had a torrent of oil in the valley but none into the rocker shafts. I pulled the heads, used a coat hangar and probed the oil galleys in the heads. I found they didn't go strait through, but with shop air I had air circulation. What stumps me is why? I have to wait till late next week to get back on it.
Many thanks
