John, thank you and your staff for the wonderful job you did on my 6.0 cylinder heads. My mechanic thought they looked absolutely wonderful. We’re still working on the tunes. The truck runs wonderfully; it makes lots of power. I’m glad that I chose you guys to do my work. Just a little information: here in Virginia, we have had temperatures this winter of -8 degrees and, within 24 hours, 60 degrees. Wow, those cylinder heads will take that. Hopefully they’ll stay there for a long time. Any work that I need in the future will definitely come to you. The shipping charges are a small price to pay for such quality work.
