FAQ:
Cost: The heads were $550 plus shipping and there was about another $500 in other parts and gaskets. Time cost was about 4 days with 2 people cleaning every part and bolt.

Heads: It was a machine shop in Grand Prairie, Texas via eBay, seller name: headsonly, that the heads were purchased from. Listing Title on ebay: "DODGE CHRYSLER JEEP HEMI 5.7L V-8 REBUILT CYLINDER HEAD 2003-2008 ONLY"
They have a core return program where you give them a casting number and some info, they send you the correct set of rebuilt heads with improved valve seats, and you send your heads back in the same boxes with the return label provided. There are plenty of people doing a service like this so do some research and find a seller that you like.

Cause: This car was a classic case of cost cutting being the main factor in the valve seat failure. Making radiator end tanks out of plastic is a bad idea because they get brittle and crack with heat (this problem is accelerated with the desert heat where we live). So the radiator cracks an end tank on a hot day and the engine starts over heating very quickly causing the valve seats to drop. Don't think this would have happened if not for the radiator since the car had 207K on it at the time.
