The cylinder head forms the top enclosure of the combustion chamber and houses the valves, valve springs, and camshaft(s). It must withstand high temperatures and pressures while maintaining precise alignment. Cracked or warped heads cause compression loss, coolant leaks into cylinders, and severe engine performance issues. We offer both complete reconditioned cylinder heads and bare castings for major engine families. Our heads are machined to exacting tolerances, ensuring flat sealing surfaces, true valve guides, and optimal combustion chamber volume for restoring engine power, efficiency, and reliability.
