All the things suggested here are good candidates to check out, but the radiator should be at the top of the list. As an engine ages and accumulates miles, the amount of friction it produces gradually reduces due to piston ring wear, etc. At the same time the radiator also looses efficiency but isn't noticed because it's dealing with less and less heat. When you rebuild the engine, you're back to a maximum heat load which the aged radiator can no longer handle. I'd pull the radiator and take it to a competent shop for cleaning and evaluation of its flow rate and overall condition.
