Cometic C5332-066 GM Gen V/VI Big Block V8 MLS Head Gasket 4.375" Bore

The Cometic C5332-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for GM Generation V and VI Big Block V8 engines. This high-performance gasket features a 4.375-inch bore diameter and a compressed thickness of .066 inches, providing superior sealing under extreme pressure and temperature conditions.

Key Features:

• Multi-Layer Steel construction for maximum durability and heat resistance
• 4.375-inch bore diameter for proper combustion chamber sealing
• .066-inch compressed thickness for optimal compression ratio
• Engineered specifically for GM Gen V/VI Big Block V8 applications
• Superior sealing performance compared to composite gaskets
• Resistant to blowout and coolant leakage under high boost and compression

Cometic MLS head gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that can withstand extreme cylinder pressures found in high-performance and racing applications. The embossed sealing beads provide targeted clamping force around critical sealing areas including combustion chambers, coolant passages, and oil return holes.
