In the Central Valley of California a really good shop is JTS Truck Repair in Bakersfield, Ca. (661) 847-1777, 4300 Saco Rd. A Side road parallel to HWY 99 north of 7th Standard/ Merle Haggard BLVD. If you think what you did to your diesel is bad just wait and see what they haul off of the hwy with the 18 wheelers. I have had them work on both my 7.3 and 6.0 fast and a fair deal. The service manager used to work at International.
