Head Gasket - RH Ford 4.6L

The Head Gasket – RH Ford 4.6L is a critical engine seal designed for the passenger-side cylinder head on Ford's legendary modular V8 engine platform. Whether you're rebuilding a 2-valve or 3-valve 4.6L engine after high-mileage wear, addressing a cooling system leak, or restoring power after gasket failure, this component is essential to maintaining compression integrity and preventing coolant crossover. Ford 4.6L engines power everything from Mustangs and F-150s to Explorers and Crown Victorias, making this gasket a frequent maintenance requirement for serious enthusiasts and professional mechanics alike.

This multi-layer steel gasket features a 3.625-inch bore diameter engineered to match Ford's modular cylinder head port geometry precisely. Multi-layer steel construction combines durability with heat dissipation—critical under the sustained combustion temperatures and pressure cycling that modern engines endure. The gasket's engineered composition prevents blowout at the head-to-block interface, resists coolant permeation, and maintains a reliable seal across thermal cycles without requiring constant re-torquing. At 0.74 lbs and measuring 22.65 × 9.55 × 0.55 inches, it fits standard head bolt patterns and torque specifications for all second-generation 4.6L modular engines.

Mechanics and engine builders trust this gasket for both OEM-spec restorations and performance builds where reliability cannot be compromised. Installation requires proper head bolt torquing sequences and cleanliness protocols to ensure maximum gasket life—a straightforward job for those with basic engine disassembly experience. Whether you're addressing a known leak, performing preventive maintenance on a high-mileage 4.6L, or completing a full cylinder head refresh, this right-side gasket pairs seamlessly with a corresponding left-side unit for complete top-end sealing.
