Cometic C5323-040 GM Small Block MLS Cylinder Head Gasket Bore - SB2.2 V8 4.165

The Cometic C5323-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM SB2.2 small block V8 racing engines. This gasket features a .040" compressed thickness and is designed for a 4.165" bore diameter, making it ideal for performance and racing applications requiring precise sealing under extreme conditions.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .040" compressed thickness provides optimal compression ratio tuning
• 4.165" bore diameter designed for GM SB2.2 small block V8 engines
• Includes steam holes for proper coolant circulation
• Engineered to withstand high cylinder pressures and temperatures
• Provides excellent combustion sealing and resistance to blow-out

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technologies to create a gasket that recovers quickly from compression and maintains consistent sealing pressure. The embossed layers create a micro-seal around combustion chambers, coolant passages, and oil passages, making these gaskets the preferred choice for professional engine builders and serious racers.
