After the engine was sent south, the valve covers and 1 head were removed for inspection. There was a small amount of rust present in the cylinder. Probably from moisture entering the intake. Both blowers are rusted and need rebuilt. The mechanic said he oiled all the cylinders at that time, and parts were reinstalled.
Recommend removing the heads and pan for cleaning and inspection. The motor should be in excellent condition with very low hours (1100 apx.), except it will need some disassembly and cleaning because of long term storage.
The unit is in Idaho. And any interested party should inspect it.
