My guess is the cam was warped.) But with the cam beaking like that at what was probably highway speeds, valves are shot, block must be a disaster. Don't dump any money into trying to get this fixed. If you need piece of mind, find someone to pull the head and do a quick biopsy of the block. Then try and salvage whatever may be usable and sell the parts. The IP should get you a few bucks on ebay.
