4.670 MLS Head Gasket .060 - BBF 460

The Cometic Gaskets 4.670 MLS Head Gasket .060 - BBF 460 is a precision-engineered cylinder head gasket designed specifically for Big Block Ford 460 engines. This gasket serves as the critical seal between the cylinder head and engine block, preventing coolant and oil leakage while maintaining compression integrity under high heat and pressure. Builders and engine shops rely on quality head gaskets to ensure engine longevity and reliability in both street and high-performance applications.

Manufactured by Cometic, a leader in advanced gasket technology, this head gasket features a multi-layer steel (MLS) construction that provides superior sealing performance compared to traditional fiber gaskets. The 4.670-inch bore diameter is precisely engineered for BBF 460 compatibility, while the 0.060-inch compression thickness ensures proper combustion chamber volume and head clamping force. MLS gaskets excel at accommodating the surface irregularities inherent in aluminum and cast-iron heads, distributing clamping load evenly across the sealing surface to prevent blow-out and mid-range leakage.

Engine rebuilders and performance enthusiasts restoring or upgrading Big Block Ford 460 engines benefit from the reliability this gasket delivers. Whether you're assembling a stock rebuild or a modified performance engine, proper head gasket selection is non-negotiable for long-term durability. Installation requires careful block and head surface preparation, correct torque specifications per your engine manual, and use with quality head bolts. This gasket is sold as an individual unit and is recommended for use with appropriate sealants and proper installation techniques to achieve optimal sealing performance.
