Cometic C5410-040 MLS Cylinder Head Gasket for Chevy Small Block - V8

The Cometic C5410-040 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Generation-1 Small Block V8 engines. This high-performance gasket features a .040" compressed thickness and is optimized for Vortec cylinder heads with a 4.165" bore diameter.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability under high combustion pressures
• .040" compressed thickness allows for precise compression ratio tuning
• 4.165" bore diameter accommodates standard and slightly overbored small block applications
• Valve pocketed bore design ensures proper clearance for valves and combustion chamber geometry
• Engineered specifically for Vortec cylinder heads for optimal fitment and sealing
• Stainless steel construction with elastomeric coatings resists corrosion and prevents leaks

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a gasket that conforms to imperfections in the sealing surface while maintaining structural integrity. This design makes them ideal for high-performance and racing applications where cylinder pressures exceed stock levels. The gasket's construction allows for engine movement and thermal expansion without compromising the seal, making it an excellent choice for street performance and competition engines alike.

This gasket is compatible with Chevrolet Small Block V8 engines including 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 cubic inch variants equipped with Vortec heads. The valve-pocketed design accommodates the larger valve dimensions found in Vortec cylinder heads.
