After heads are removed- inspect cylinder walls. Do you see crosshatch from previous machine work? If yes, this would indicate little wear in the bores. If not, how much ring ridge can you feel? Look at burn pattern on top of each piston. Are they consistent? Turn engine over and remove pan. Remove two rod caps from a crank journal. Inspect crank journal and connecting rod bearings. Remove one main bearing cap. Inspect crank journal and main bearing. By now you should be seeing the condition of the motor and where you need to go with it. Is there rust in critical places? Has water been sitting in the motor? You can mic the bore, the connecting rod journal to see if they are standard. Good luck, you can do it.
