Took my 97 K2500 454 burb in to get the heads redone. They did great work and even helped me with a seperate problem twice at no extra charge. The stopped on a paying job to help me out for free and even offered to change the part (free labor)for free! The guy removed the Idle Air Control cleaned it and reistalled for free. That was my problem. I wund changing it myself since they were busy and I did not feel right for them to stop a paying customers project to do something I could change easily. Good group of guys to deal with and a great price and warranty. I will return (hopefully it will be no sooner than a few years) to them for more work and will refer friends as well.
