Featuring a 4.290-inch bore diameter and .040-inch compressed thickness, these gaskets are engineered to provide superior sealing under extreme cylinder pressures and temperatures.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum durability and reliability
• 4.290-inch bore diameter for precise fitment
• .040-inch (1.02mm) compressed gasket thickness
• Sold as a pair for multi-cylinder applications
• Includes integrated oil and coolant sealing passages
• Superior torque retention and reusability compared to composite gaskets
• Engineered for high-performance, racing, and forced induction engines

Cometic MLS head gaskets feature multiple layers of stainless steel with a Viton rubber coating that provides exceptional micro-sealing at the head-to-block surface. The embossed sealing beads around combustion chambers, oil passages, and coolant jackets ensure leak-free operation even under extreme conditions. These gaskets are ideal for engines with increased compression ratios, boost pressure, or nitrous oxide applications where OEM gaskets may fail.
