The machine shop I used in the past had closed to the public. Needed a valve job done on a K20 head. Brian was recommended by my coworker and boy am I glad I found out about Extreme Speed. I could tell his hands were full but he got me in and out in a day. Highly recommended!

Dont waste your time calling other shops. This guy is hands down the best there is. He did great work on my 2JZ head with next day turn around. Price was great taught me some things and saved me money in the process. My cylinder head looks brand new. Theyll also do flywheels. I will bring my future projects back to him. Thanks.

One of my friends found Brian a few years ago for head work. Ever since then we have taken our 4 cylinder race heads to be assembled by Him. He stands by his work and it’s extremely affordable. His prices and quality are unbeatable in the Milwaukee area. He assembled my s2000 head within 3 weeks of me dropping it off in peak season. Will definitely continue to come here for any head work I need done.

Very honest and friendly. Took the time to talk with me and explain the process about reconditioning a head. Very fair pricing and quick turn around time. Would highly recommend.

Did great work on the heads I had milled there. Also had them do a valve job. Heads came back looking like brand new. Turned them around in a couple days and the price was very fair. Cant ask for more than great work at a fair price.

If you need to get your heads milled and clean extreme speed is the place to go very professional quality work at a great value too. I highly recommend him...

Did a great job on the head for my boat motor. Very reasonably priced and good turn around time. Thank you, my boat is running perfect!

Brain is by far the best cylinder head guy in the area. He is extremely fast and knows his stuff. Would not hesitate to go back. Will not use anyone but Brian for my cylinder head work in the future. By far the best!

Got my Honda head perfect!

A good friend of mine turned me on to Extreme Speed. Brian is one of the nicest and most helpful person I have ever dealt with in the automotive industry. Prices and turn around time are awesome. Wish I would have known about Extreme Speed many years ago.

Brian does great work and is affordable with a quick turnaround time!

The only place I will ever go for cylinder head repairs. Workmanship is always spot on, awesome to work with. And very fair prices!!!!

Always a pleasure to work with.Great workmanship and price’sThe best I’ve found anywhere

Quality work at an affordable price. Quick turn around allowed me to finish the repair I needed to do and get my customer back up and running. Thank you!!

Brian is a super nice guy and very professional!!

My compression test came up perfect once installed.. though there was some light scratches on the head i observed after picking it up... aside from that they were slightly... weird? nothing direct or aggressive just some weird comments on my name.

Awesome price! Great guy!

Ive used this shop more than a few times now. From power sport heads to automotive heads, they do a great job! Fast turn around time as well!

Awesome place, reasonable prices, strongly suggest.
