Answer
Mike, blown head gaskets on CX500s are not unheard of, but I would definitely change the thermostat first, then be sure that you bleed all the air out of the system and check the fan for damage. CX500 fans tended to crack at the hub, causing them to wobble around, making a lot of noise.

Electrosport in SoCal has replacement stators for CX500-650s.
