4.500 MLS Head Gasket .040 - BBF 460

The 4.500 MLS Head Gasket .040 for Big Block Ford 460 engines is designed for serious engine builders and mechanics working on classic and high-performance BBF platforms. This gasket is essential for ensuring reliable cylinder-head sealing during engine rebuilds, performance upgrades, or restorations where precision is critical.

Constructed from Multi-Layer Steel (MLS), this gasket offers superior sealing integrity compared to traditional composite options. The precision-stamped steel layers with elastomer facings create a robust barrier that withstands extreme pressure and thermal cycling, preventing deformation and blow-by. The .040-inch thickness is standard for 460 cylinder head work, ensuring proper deck height and compression ratio.

Ideal for both stock replacement and modified engines, this gasket is particularly beneficial for those running elevated compression or boost. Cometic's manufacturing process guarantees consistent density and facing integrity, which is crucial for preventing coolant leaks and combustion gas escape. This gasket is a reliable choice for street and strip applications, outperforming older gasket materials.
