After a 2 month solid trial period after the head work was done I am more then satisfied with the repair/work Jeremy and chris had done to my truck. I had head issues after I install compound turbos on my 2005 Dodge Ram 3500, and Jeremy referred me to an outstanding cylinder head shop which completely rebuilt/resurfaced the head. After the head was finish I had Jeremy and Chris add the fleece coolant bypass and arp 625+ head studs installed. After getting the truck back I looked over the work that was done, and I am more than satisfied with how the put the truck back together. After "rigorous" test of 75lbs of boost, I can say these guys are more than qualified to build a high powered Cummins. I've had terrible experiences with other diesel shops and finally I found good honest diesel mechanics that go out of there way I can trust!!!! Thanks again Jeremy and Chris for the solid trusted service you provided for me. These guys are my go to guys for any other performance/ fixes I may need in the future! - Daniel F.
