Except where noted as being recommended by others, I've used each of these machine shops and have been very satisfied with the work performed and prices charged. These are not boutique machine shops. If you want a machine shop where you can sip your latte in a spotless lounge and pay inflated prices, look elsewhere. These are solid, trustworthy machine shops that do real work for real people.

The listings here should be considered good places to get solid machine work done at a reasonable price. However, they should not be considered the top-of-the-line, used by go-fast-racers everywhere, best of the best. If you are looking to squeeze every bit out of your engine, want to have your heads ported, and have the best of the best done, then you need to contact Mike Rich Motorsports. Mike Rich is fantastic. This isn't to say that the folks listed below aren't qualified. The ones I've used are and I've been happy with them. I mention this only because I don't want you to expect these guys to give you top-shelf heads for bottom basement pricing. They'll do a basic service (valves, guides, grind, shim for spring pressure, etc) and send you on your way without a lot missing from your wallet.

If you don't live near one of the shops I list below, you should probably find somebody local. There are good machinists everywhere and there is really no reason to ship your stuff across the country just because I mention that they've done good work for me. If you own an older machine, you are going to need a machinist. Best to find one local that you trust.
