the gears will clean up good----cam--I would use a new one to be safe---this one will clean up, BUT how many hours does it have on it?--who knows, so new one there to be safe!
new oil pump a must and you could go new water pump since you are there.
Mic. the crank and also the piston bores to see IF need machine shop visit or not. ----could get lucky on them just never know.
Ya that motor had rain water sitting in it big time! ---sad how some guys treat their equipment! I bought several tractors with same deal---water in pistons and motors stuck!
Your making progress for sure! ---stay with it!!
