"JEEBUS" No. 2 !
Looking at all the heavy corrosion found in the tappet chambers on the previous page, this engine needs to be removed and placed on a stand and disassembled. Even if it turned over, it's in no shape to run with all that crap in there. There is likely corrosion that you can't see that is locking up the rotating assembly. The block needs to be thoroughly cleaned - baked, tanked, blasted, and inspected before proceeding. You might already have a boat anchor on your hands, but you won't know until you can have a shop inspect it. I'm trying to save you time from making more snausage here. Hopefully it's still good!
