Can anyone recommend an independent diesel shop in the Tulsa area?

I'm out of warranty and think my truck may need head gaskets. Want new style head bolts installed, and Ford dealer may not be able to do so. Also don't want trouble over EGR valve again. I've been forced to buy two (2) of these crappy parts that won't make it a month without trouble. I guess Ford mechanics are forced to make this part functional (by replacing it) whenever I go in for service on the engine.
