Cylinder Head

Genuine OEM Cylinder Heads

The cylinder head seals the top of each combustion chamber and houses the valvetrain, so cracks, warping, or a blown gasket surface here directly affect compression and power. Common signs are coolant mixing with oil, white smoke from the exhaust, overheating, or a noticeable loss of compression and power. A generic head rarely matches the exact port geometry, valve seat angles, and casting tolerances of the original design, which can cause poor sealing or compatibility issues with existing components. That's why every cylinder head in this collection is genuine OEM, matched to the manufacturer's original part number.
