New Ford 2.9L Cologne V6 Ranger Bronco II Cylinder Head

New Ford 2.9L Cologne V6 Ranger & Bronco II Cylinder Head

New OEM-Quality Replacement Heads For Ford 2.9L V6 Engines

Restore your engine’s mechanical integrity with this all-new 2.9L Cologne V6 cylinder head, specifically engineered for Ford Ranger and Bronco II applications. This fresh, high-nickel iron casting features reinforced water jackets and an upgraded deck thickness to eliminate the thermal stress cracking common in original thin-wall factory units. Although the gasket surface is pre-milled, every head undergoes an in-house precision verification to ensure the Surface Roughness (Ra) meets the strict requirements for modern sealing standards. 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 high-heat reliability, this head provides a professional-grade solution for long-term cooling system and compression 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.
