The DK-GMLMM-CHL is a complete, ready-to-install assembly — not a bare casting or remanufactured unit — that comes fully loaded with a new valve train, including black nitride-coated valves for superior durability and wear resistance.

Why Choose This Loaded LMM Cylinder Head?

• Brand New Construction — Fresh OEM-style casting with precision machining, flatness verification, and pressure/leak testing. No core charge and no surprises from previous engine damage.
• Fully Loaded Valve Train — Includes new valves (black nitride coated for excellent heat and wear resistance), valve springs, seats, seals, retainers, and keepers. Saves hours of labor compared to rebuilding old heads.
• Ready to Bolt On — Pre-assembled and ready for installation with a new head gasket and head studs (ARP or equivalent recommended for performance/reliability builds).
• Optimized for LMM Demands — Designed to handle the combustion pressures, heat, and EGR/DPF stresses of the LMM while delivering excellent sealing and airflow.
• Ideal for Repairs or Builds — Perfect for fixing cracked or damaged heads, or as a solid foundation for a performance rebuild.
