Spins easy? I'd wager a blown headgasket and depending on how severely over heated, i'd guess cracked block or head.

Agree on head gasket...PCM will shut down the motor on excessive overheat condition. That usually will save the motor mechanically. If you yank the head, send it to a shop to be magna fluxed for cracks and they can check for warp....
