We offer machining of cylinder heads for heavy-duty, off-road construction equipment, semi-tractor trailers, oil patch equipment, generators, field equipment, tractors, and combines. Please note: these services are not for passenger vehicles.
After being disassembled and cleaned, the castings and parts go through a stringent testing procedure that establishes re-usability. Valve seats are no longer ground, but rather, are cut with a pre-set 3 angle cutter that ensures proper concentricity and precise contact width, every time. Valves that can be reused are ground using a Collett Holder (racing industry application!) to obtain perfect geometry.
We know that choosing the lowest price in reconditioned cylinder heads encourages the reuse of parts that are nearing their wear limits, or parts that are worn. Choosing heads that are repaired with outdated equipment and inferior technology will result in components with a shorter life expectancy.
