Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
• .045-inch compressed thickness for optimal deck height and compression ratio tuning
• 4.165-inch bore diameter accommodates standard and slightly overbored small block engines
• Valve pocketed bore design ensures proper clearance for performance cylinder heads
• Compatible with both 18-degree and 23-degree cylinder head angles
• Steam holes included for proper coolant circulation and thermal management

Cometic MLS gaskets are constructed from multiple layers of stainless steel with elastomeric coatings that allow the gasket to conform to imperfections in the sealing surfaces. This advanced design makes them ideal for high-performance applications, forced induction setups, and street/strip engines where durability and reliability are critical. The valve pockets provide clearance for aftermarket performance heads without requiring additional machining.
