Cometic C5269-075 MLS Cylinder Head Gasket Chevy Small Block Bore - for V8 4.060

The Cometic C5269-075 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 .075" (1.9mm) compressed thickness and is manufactured to accommodate a 4.060" bore diameter, making it ideal for mild overbore applications and performance rebuilds.

Key Specifications:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• Compressed thickness: .075" (1.9mm)
• Bore diameter: 4.060"
• Compatible with 18-degree and 23-degree cylinder head designs
• Valve pocketed bore design for performance valve clearance
• Fits Chevrolet Generation-1 Small Block V8 engines (262-400ci)

Advanced MLS Technology:

• Multiple layers of stainless steel with elastomeric coating provide maximum sealing capability
• Exceptional resistance to extreme cylinder pressures and temperatures
• Compensates for minor surface imperfections and thermal expansion
• Superior blow-out resistance compared to traditional composite gaskets
• Reusable in many applications when properly installed and removed

Cometic MLS head gaskets are the preferred choice for high-performance and racing applications where reliability under extreme conditions is critical. The valve pocketed design ensures proper clearance for larger valves commonly found in performance cylinder heads, while the precision bore sizing maintains optimal combustion chamber sealing. Compatible with both stock and aftermarket cylinder heads featuring 18-degree or 23-degree valve angles.

Installation Notes: MLS gaskets require smooth surface finishes (typically 50 RA or smoother) on both the block deck and cylinder head surfaces for optimal sealing. Follow manufacturer torque specifications and sequence recommendations for your specific engine application.
