The .045" MLS Head Gasket from Cometic Gasket is specifically engineered for Big Block Chevy engines, covering the popular 396 to 502 cubic inch range. This multi-layer steel (MLS) gasket is designed to provide enhanced sealing capabilities and increased resistance to blowouts, making it an ideal choice for both street and race applications. The head gasket’s design ensures a consistent and reliable seal between the cylinder head and engine block, which is critical for maintaining optimal performance and efficiency.

Constructed from high-quality materials, this head gasket can withstand extreme temperatures and pressures commonly found in high-performance engines.
