    The TECHCENTER Online is Now Open

    We've just published our first article, "Ford 6L Diesel Head Teardown". For this article, a demo head was built with each cylinder position used to highlight different stages of a typical Ford Diesel head rebuild. We see a lot of these heads and have come up with a number of solutions from a basic rebuild/restoration to ways to increase the compression, performance and durability of your Ford diesel.

    Visit the TECHCENTER and give us a call or drop us an email. We'll be happy to talk to you about the different options for your Ford diesel.

    Our New Rottler SGF8 - Seat and Valve Guide Machine

    Rottler's SGF8 Valve Seat and Guide machine can handle even the most complex multi-valve cylinder heads with ease. What's more, this machine provides the highest degree of valve/seat concentricity in the industry today. Rottler's rigid precision carbide centering pilots are manufactured to less than one-tenth tolerance. Combined with the lightweight air float work head, it gives perfect centering in the valve guide and the best concentricity of the valve seat to the guide.

    UCF is committed to providing the finest rebuild services in the country.

    Cummins® Performance Diesel and Power Stroke® Diesel

    New ItemCheck out our Cummins performance diesel cylinder head packages. The Cummins diesel is one of the strongest diesels on the market. If you are looking for a boost in power, efficiency, and better fuel mileage, check our performance packages. STAGE 1 and STAGE 2 provide a substantial boost in power. STAGE 3 and STAGE 4 packages are for those interested in maximizing the power and efficiency of their diesel. Check here for details.

    Diesel engines undergo a tremendous amount of stress in day-to-day operations. When the time comes for that rebuild, we take the extra steps necessary to create the highest level of compression and durability. Unlike most machine shops, we stress each block with custom BHJ© Torque Plates which duplicate the stresses on the block when it is assembled. Only then do we machine the cylinder block, assuring that tolerances will not be affected and internal dimensions distorted when the engine is reassembled.

    We are one of the few machine shops nationwide that offer the BHJ© Torque Plate system.


    We offer the following services and more. We service both foreign and domestic engines and drive trains.


    VISA®—MasterCard®—Discover® accepted.
