Best prices and customer service on Duramax LML heads out there. Shipped fast and very cool about how long it took to get the cores back.

Parts arrived as promised. Ported heads gave me that low end torque and high rev HP I was looking for! ...if only I did the cam at the same time.

New Ford 6.0L Powerstroke Turbo Diesel 18mm Cylinder Head with O-Ring Upgrade

Premium OEM-Quality Replacement with Enhanced O-Ring Sealing

Restore your engine’s mechanical integrity with this all-new 18mm 6.0L Powerstroke cylinder head, specifically engineered for 2003–2006 Ford Super Duty and Excursion applications. This fresh, high-density casting features a precision-machined O-ring upgrade, utilizing a stainless steel wire to create a secondary mechanical seal that bites into the head gasket—drastically reducing the risk of combustion leaks under high-boost and high-cylinder-pressure conditions. Although the gasket surface is pre-milled, every unit undergoes an in-house precision verification to ensure the Surface Roughness (Ra) meets the strict requirements for high-clamping Multi-Layer Steel (MLS) gaskets. We perform final guide sizing and multi-angle valve seat cutting on our Rottler equipment to ensure perfect valvetrain geometry and a 100% airtight seal. Pressure tested to 60 PSI and built for ‘bulletproof’ reliability, this head provides a professional-grade solution for long-term cooling system and combustion integrity.

🛠️ In-House Machining Process

  • Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils, metal shavings, and manufacturing debris. This ensures your oiling system remains uncontaminated from the first start-up.

  • In-House Precision Machining: Unlike “shelf-stock” heads, we perform all final machine work in-house. This includes final guide sizing and precision valve seat cutting to ensure perfect geometry and clearances before the head reaches the assembly bench.
  • Pressure & Integrity Testing: To go beyond the factory standard, we pressure-test every head to 60 PSI. This verifies that the casting is free of porosity leaks or internal defects that could compromise the cooling or oiling systems.

  • Dimensional Inspection: Our technicians perform a multi-point inspection of the gasket-sealing surface and bore alignment. This ensures the head is perfectly flat and meets tight OEM tolerances for a flawless fit.

  • Professional Assembly & Setup: Valvetrain components are installed and verified in a clean-room environment. We check spring heights and seal seating to ensure the assembly is balanced and ready for high-performance use.

  • Vacuum-Seal Verification: Every intake and exhaust port is Vacuum Tested. This guarantees a 100% airtight seal between the valves and seats, ensuring maximum compression and peak performance right out of the box.
