94mm MLS Head Gasket .030 - Ford 4.6L LH

The Cometic Gaskets 94mm MLS Head Gasket .030 – Ford 4.6L LH is a multi-layer steel cylinder head gasket engineered for the left-hand bank of Ford modular 4.6-liter engines. This component is critical for maintaining compression seal integrity and preventing coolant or oil bypass across the combustion chamber interface. The 0.030-inch compression thickness is a precise specification designed to match Ford's factory deck height and combustion chamber geometry on the driver's side of the engine.

Multi-layer steel (MLS) construction delivers superior sealing performance over single-layer gaskets by employing multiple embossed steel layers that compress consistently under cylinder pressure. The 94.0mm bore diameter corresponds precisely to Ford's 4.6L displacement and ensures proper alignment with combustion chamber edges, preventing hot spots and local pressure concentrations that can compromise gasket life. The 0.030-inch thickness is a common factory specification for naturally aspirated and lightly boosted 4.6L applications, though verification against your specific engine configuration is recommended before installation.

This gasket is intended for OEM replacement, engine rebuilds, and performance restorations on Ford modular-platform vehicles. It addresses the left-hand (driver's side) cylinder head, so a matching gasket for the right-hand bank is required for a complete head gasket set. Proper installation requires correct fastener torque sequence, clean deck surfaces, and appropriate sealant application per Cometic and Ford specifications.

When sourcing head gaskets for 4.6L Ford engines, matching the correct bore diameter, compression thickness, and bank position is non-negotiable. MLS gaskets are the modern standard for this application, offering improved reliability over older composition designs and greater resilience to thermal cycling.
