5 /5 Joseph Kogut: I brought in a 1992 Miata 1.6L head that had warped after overheating due to a coolant leak. One of their technicians helped me at the counter. I asked to have the head cleaned, and resurfaced, and at his recommendation, I also agreed to have it pressure tested. The job was done a day in advance of their estimate, for less money, and the finish on the machining was impeccable. I also accidentally left a dowel in the head, and he was nice enough to save it and leave it taped to the head after the work was done. Im impressed with the quality of their work, and their service. The car is running great, and I wont hesitate to use them again.
