M & M Head Services at 30 Reid Street, Delaware, Ohio.

I can't say enough about Mike and his guys. I dropped off a set of heads and an intake on a Tuesday right before they closed. He called me Wednesday to advise that the heads were bad (which I assumed) and had a new set to me ready to install, with a clean intake, on Thursday afternoon. Workmanship was great, price was more than fair, and he took the time to walk me through everything they had done. I won't use anyone else for engine work again. Thank you!!
