Mitsubishi 4D56U 4D56Di-T Cylinder Head – Challenger Triton

Machine or surface your cylinder head.
Please note that the valves must be set to a specific value below the cylinder head face. When we machine or surface your head, the valves move closer to the face, which may cause them to hit the pistons. Suppose the valve depth is out of specification; we may be unable to machine the face without reseating the valve, and we will require a complete service.
