Cometic C5567-066 Chrysler Race Block MLS Cylinder Head Gasket Bore - R3 4.100

The Cometic C5567-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler R3 race blocks with W2 cylinder heads. This high-performance gasket features a 4.100-inch bore diameter and 0.066-inch compressed thickness, making it ideal for high-compression racing applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
• 0.066-inch compressed thickness allows precise compression ratio tuning
• 4.100-inch bore diameter optimized for race-prepared Chrysler engines
• Engineered specifically for Chrysler R3 race blocks with W2 cylinder heads
• Exceeds OEM specifications for high-performance and racing applications

Cometic MLS gaskets feature multiple layers of stainless steel with active seal technology that responds to combustion pressure and temperature changes. The embossed layers create a seal that actually improves as cylinder pressure increases, making these gaskets the preferred choice for serious racers and engine builders working with forced induction, nitrous oxide, or high-compression naturally aspirated builds.
