6.0 Powerstroke 20MM Loaded Cylinder Head – DK Engine Parts (DK-FD6.0-20CHL)

This is ONE (1) cylinder head — sold individually.

Restore strength and reliability to your late-model 6.0L Powerstroke with the DK Engine Parts 20MM Loaded Cylinder Head. Designed specifically for 2006–2007 6.0L engines that use the larger 20mm head dowel pins, this head is a major upgrade over factory and remanufactured options.

Why This Head Stands Out

Factory 6.0L cylinder heads are notorious for cracking around the glow plugs and valve seats, leading to blown head gaskets, coolant intrusion, and overheating. The DK-FD6.0-20CHL solves these problems with a brand-new, improved casting that reinforces the factory weak points.

Unlike remanufactured heads that simply patch old castings, this is a fresh casting built tougher from the start.

Key Features & Benefits

• Reinforced New Casting — Extra strength around glow plugs and valve seats to resist cracking under heat and pressure.
• Fully Loaded & Ready to Install — Comes completely assembled with all-new valvetrain components, saving hours of shop time and labor.
• 20mm Dowel Pin Compatible — Precision fitment for 2006–2007 engines. Using the correct dowel size is critical for proper head gasket alignment and sealing.
• Includes Hardened Valve Seats & Injector Cups — Built for long-term durability.
