4.080 MLS Head Gasket .027 - SBC Vortec

The 4.080 MLS Head Gasket .027 - SBC Vortec by Cometic Gaskets is a precision-engineered cylinder head gasket designed for small-block Chevrolet Vortec engines. This multi-layer steel gasket serves as a critical seal between the cylinder head and engine block, preventing coolant and combustion gas leakage while maintaining compression integrity. Whether you're rebuilding a classic performance engine or restoring factory Vortec power, a quality head gasket is essential to engine reliability and longevity.

Constructed from advanced multi-layer steel (MLS) material, this gasket features a 4.080-inch bore diameter and 0.027-inch compression thickness, allowing it to maintain consistent sealing pressure across a wide range of engine conditions and cylinder pressures. The MLS design provides superior gasket recovery and conformability compared to traditional single-layer gaskets, reducing the risk of head gasket failure even in high-performance or boosted applications. Cometic's manufacturing precision ensures dimensional accuracy and reliable performance, critical factors when resurfacing and assembling Vortec cylinder heads.

This head gasket is ideal for engine builders, performance enthusiasts, and technicians rebuilding small-block Chevy Vortec engines for street, marine, or racing applications. Proper installation requires careful surface preparation of both the head and block deck, correct torque sequencing, and adherence to manufacturer specifications. The 0.027-inch thickness specification makes this gasket compatible with standard Vortec head and block combinations, ensuring proper combustion chamber volume and compression ratio calculations during engine assembly.
