Cometic C5411-027 MLS Cylinder Head Gasket Chevy Small Block Bore - for V8 4.060

The Cometic C5411-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines. This precision gasket features a .027" compressed thickness and is designed to accommodate a 4.060" bore diameter, making it ideal for engines with overbored cylinders or performance builds requiring larger bore sizes.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
• .027" compressed gasket thickness for precise compression ratio tuning
• 4.060" bore diameter accommodates overbored or stroker engine configurations
• Valve pocketed bore design ensures proper valve-to-gasket clearance
• Specifically designed for Vortec cylinder heads with correct port alignment
• Embossed stainless steel layers with Viton rubber sealing beads resist heat and combustion pressure

Cometic MLS gaskets are the preferred choice for performance and racing applications where conventional composite gaskets cannot withstand extreme cylinder pressures and temperatures. The multiple layers of stainless steel distribute stress evenly while maintaining the micro-seal necessary for leak-free operation. 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 when equipped with Vortec heads and machined to a 4.060" bore.
