109mm MLS Head Gasket LH .040 Ford 7.3L Godzilla

The 109mm MLS Head Gasket LH .040 for Ford 7.3L Godzilla engines is designed for builders and mechanics who are pushing the limits of Ford's renowned big-displacement platform. This high-performance gasket is essential for applications where factory gaskets may fail, particularly in high-horsepower builds. Whether you're constructing a street engine, truck platform, or competition powerplant, a reliable head gasket is crucial to prevent coolant leaks and combustion gas bypass.

Constructed from Multi-Layer Steel (MLS), this gasket offers superior sealing performance compared to traditional composition gaskets. The .040-inch thickness is precisely engineered to match the head surface finish and combustion chamber design of the 7.3L Godzilla engine, ensuring consistent clamp load and minimal gasket creep under high RPMs or sustained boost. MLS gaskets are built to withstand extreme cylinder pressures and temperature fluctuations, making them ideal for aggressive tuning.

Serious builders of the 7.3L Godzilla engine—those upgrading to stroker builds, turbochargers, or superchargers—rely on Cometic gaskets to maintain durability during dyno sessions and high-mileage use. The left-hand (LH) orientation of this gasket is crucial for proper installation, so verifying fitment is essential. With its advanced design, this gasket is compatible with modern fuel systems and coolant formulations, ensuring optimal performance.
