Spridget problem

I had to tow a friend of mine home today. He lost power this
afternoon (1500 engine) and leaked the contents of his
radiator out his tailpipe while the car naturally overheated
in short order.

What do you think the chances are that he only blew out a
head gasket?  Is it likely that he cracked the head?  It got
pretty hot.
