Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high compression and temperature conditions
• .066" compressed gasket thickness for precise deck height control
• 4.165" bore diameter accommodates stock and mild overbore applications
• Valve pocketed design provides clearance for larger valves and prevents contact

Cometic MLS gaskets are constructed from multiple layers of stainless steel, making them highly resistant to blow-out and capable of withstanding extreme cylinder pressures. The advanced design allows the gasket to recover and maintain its sealing integrity through repeated heat cycles, making it an excellent choice for high-performance street engines, racing applications, and forced induction builds.
