I've had previous engine machine work done from there at Schmitt Automotive and it's been shitty results. They do good work as far as balancing parts goes. But they fucked up a cylinder head for me and basically lied about being able to install bigger seats for me. I used to recommend they but no longer. I now use Richard's Cylinder Head Service for all my engine machine work. They punched out a block for me and serviced a cylinder head last year for me and are currently doing some machine work for me right now on a high compression head for me. Highly recommend them and reasonable prices also!
