You won't find a higher quality shop. He went above and beyond for me. Look no further if quality is your main concern.

Got my job done when he said he would, and charged me less than he quoted me. Really did a great job.

I use MT high to repair all are cyl heads on the Cummins ISLG natural gas engines in our fleet. If your running natural gas you know the issues. They are very fast and help me get my truck back up and running and are always priced right for the quality that they provide.

Needed my tubular exhaust manifold and my aftermarket intake manifold to be resurfaced and they did it no problem. Took about a week each to complete. Definitely going here again in the future

Brought in my Honda engine to this machine shop about a year ago and have had problems with the work they did ever since. Cylinders were never measured and if they had been they would have clearly seen that it needed to be bored over instead a basic hone job. With that basic hone job they used a rougher grit then is specifically needed for the job. Time wise it took longer than they had said. Talking to Bill the owner was like pulling teeth, you have to fight just to get a word in and pretty much everything is an argument. Everything you say is wrong and everything he says is right... god does this guy like to hear himself talk. Will not be bringing any more work your way.

While the gentleman was friendly he kept pushing for me to buy their “treated” gaskets for a simple mild motor. I did not bring my business here as I decided to go with a different company that doesn’t want to try to keep selling me far more than I require for my truck. All I wanted was the darn motor machined, nothing else to complicate and expand my investment on an already pricey motor to build.

I haven't bought anything from them. But Bill really educated me on O ringing and Fire ringing. I'm not even in his home state. Was on the phone for 30 mins learning!! Awesome customer service. Wish we had a shop like his in southern California. Thanks Bill!
