I kept getting an error message when I posted an answer to the original post so am posting a new message.
When I put my Cub together a couple years ago I did not use a sealer on the head bolts because they don't go throught to the water jacket like some of the other IH tractors with studs. If they did, I think you would many times have a leak when you retorque the bolts after first warming up the engine. As to sealer on the head gasket, mine said not to put any sealer on it, but some people use aluminum paint or I have used special head gasket sealer from and auto parts store. Roger
