Not really but he will have to replace the valves and get the compression checked because the rings may be shot too....plus if the valves are damaged you may as well pop the head off and take a look at the tops of the pistons just to be sure.
But then a good used engine may just be a lot easier..but before I went to that trouble I would drop it at the mechanics shop for a diagnosis first
