Midwest Cylinder Head and Machine

About Us

Midwest Cylinder Head and Machine started as Williams Cylinder Head in 1946 in Ames, Iowa. Don Williams, the founder, started the business as a general welding shop and it later grew to become specialized in cast iron welding including cylinder heads, blocks, and transmission housings. He moved his business to the neighboring town of Nevada in 1947. In 1991, Don sold the business to Rex Baker who had been working at Williams Cylinder Head since 1986 learning the business and understanding Don's vision for the business he created. After the purchase, the business continued to grow and a new 24,000 square foot facility was built in 1999 to accommodate the growth of the newly named Midwest Cylinder Head. In 2005 The Arnold Group of Companies purchased the business, combining the aluminum head rebuilding division into Midwest Cylinder Head, also adding crankshaft, connecting rod rebuilding, and engine kits to the business. With the expanded facility we were also able to bring our Military engine component work to one location.

As always, our number one goal at Midwest Cylinder Head and Machine is to provide you with the highest quality remanufactured cylinder heads and blocks available.

What We Do

We offer CNC machining, using the newest stat of the art Rottler F99Y. The F99Y is a full three axis CNC machine that allows custom programs to be written or machine blue print specifications. We can handle up to a 20 cylinder Cat 3520 block. With a Renishaw Wireless Probe we can automatically find bore centers and measure diameters, with this kind of accuracy you can be confident your machine work will be to the exacting specifications you have come to expect. The Rottler software allows for a Circular Interpolation feature that allows single point machining, the single point cutting to face counter bores and thrust faces to very accurate surface finish and geometry. In addition to all of the normal block work can use the Direct Motion program to do all of your CNC machining.

We provide our services to machine shops, auto/truck/diesel/agricultural/heavy equipment repair shops, engine remanufacturers, and individuals. We work on any size application. We weld metal so that the repair is stronger than new and send it through several stages so that is looks brand new when completed. Our ASE certified machine specialists pride themselves in making sure your engine components meet or exceed OEM specifications. We work very carefully with engines of classic cars where it is critical to the value of the vehicle to have matching numbers and we take great pride in returning to the customer a completely repaired engine block.

We offer custom crankshaft grinding to meet your specialized performance specifications. We repair just about any cast iron or aluminum part, large or small; transmission, final drive, rock shaft housings, and related items. Bring it in and we can fix it! Shipping your part in a timely and safe manner is important to us. All parts are banded over a protective covering. We make sure when it arrives at your door it is as nice as when it left ours!
