New Pair Ford 6.7L Powerstroke Cylinder Heads Early

Restore engine performance and boost efficiency for demanding heavy-duty applications

Restore your engine’s mechanical integrity with this pair of all-new 6.7L Powerstroke cylinder heads, specifically engineered for 2011–2012 Ford Super Duty applications. These fresh, high-density castings are designed with reinforced injector bores and upgraded valve seat inserts to eliminate the thermal stress cracking common in high-mileage factory units. These heads are precisely machined for Early-Model ‘White Insulator’ Glow Plug compatibility, ensuring the correct protrusion depth and heat range to prevent tip failure and combustion chamber damage. Although the gasket surfaces are 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, these heads provide 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.
