LML Duramax New Loaded Cylinder Head – DK Engines DK-GMLML-CHL (Single Cylinder Head)

Restore reliable performance to your 2011–2016 GM 6.6L LML Duramax diesel with this brand-new single loaded cylinder head from DK Engines. The DK-GMLML-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 under the high heat and pressure of diesel operation.

This is one (single) cylinder head. The LML Duramax V8 requires two cylinder heads total (one per bank).

Why Choose This Loaded LML Cylinder Head?

• Brand New Construction — Fresh precision-machined aluminum casting with verified flatness and pressure/leak testing. No core charge and no risk of hidden damage from a previous engine failure.
• Fully Loaded Valve Train — Includes new black nitride-coated valves (for excellent heat and wear resistance), plus new valve springs, seats, seals, retainers, and keepers. Saves hours of labor compared to rebuilding old heads in a machine shop.
• Ready to Bolt On — Pre-assembled and ready for installation with new head gaskets and head studs (ARP or equivalent recommended for performance or heavy towing applications).
• Ideal for Repairs or Rebuilds — Perfect solution for cracked or damaged heads, blown head gaskets, or as a solid foundation for a stock or performance engine build.
