New Castings Pair Dodge Jeep Cherokee Ram 1500 Durango Dakota 4.7L V8 SOHC Cylinder Heads (1999-2007) + Head Gaskets and Bolts

New Pair Dodge Jeep Chrysler 4.7L V8 SOHC Cylinder Heads W/ Head Gaskets and Bolts

New Castings With Hardened Valve Seats and Installation Hardware

Restore your engine’s mechanical integrity with this pair of brand-new 4.7L SOHC cylinder heads, specifically engineered for Chrysler, Dodge, and Jeep PowerTech applications. These fresh castings feature upgraded metallurgy and reinforced valve seat retention to eliminate the dropped seat and thermal cracking issues common in original factory units. Each head is precision-verified in-house, including a multi-point inspection of the pre-milled gasket surface to ensure it meets the ultra-low Surface Roughness (Ra) required for 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 before final assembly. This complete kit includes high-load head bolts and multi-layer gaskets, providing 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.
