With the coolant galleys that plugged and coating the walls, its small wonder you had a cooling problem. Several folks have now mentioned finding extensive rust on engines that appear new or little used. Clearly if the engine is not drained with the coolant drain plug (located with the large engine mounting bolts onthe center housing) and rotated to get all the coolant drained - it can be Lethal to the engine. Sorry, that was the problem, but I think your cooling system is unlikely to be a problem so at least you can proceed.
