The pan has a layer of sludge in it that won't be too bad to clean out. The valley below the intake is another story. It is really sludged pretty good. All of the valves and springs appear to be ok, but there is a lot of heavy oil deposits all over.
The main bearing caps have castle nuts with safety wire. Was this original? How can I tell if there are sleeve bearings or babbit, without removal?

The water jacket is really full of rusty deposits, which I'd like to clean out. My thought was to disassemble the complete motor, down to the block, and have it dipped to clean out. I understand that this can be a problem with the babbit bearings, that they would require re-forming and insertion, then break-in.

Any suggestions? Thanks.
