Well today I received the engine.

I will spend some time tomorrow formating photos to the scale acceptable for the forum.

After I verified it was stuck I removed the head.
Cylinder 1 had water in it and 2-6 were dry. Each cylinder has different levels of surface rust. The ridge at the top of the cylinders was about the thickness of a credit card. I could not find any indicator such as a number stamped on a piston, so no idea if it has been rebuilt.
The rocker arm assembly has a fair amount of crud build up as for the valves there is rust and carbon.

The pics will show greater detail.

For now these are the engine and head #s.

Have a good one.
