Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 4.375-inch bore diameter optimized for Chrysler Gen-2 Hemi engines
• .075-inch (1.9mm) compressed thickness for precise compression control
• Advanced composite material with stainless steel layers and elastomeric coatings
• Resists combustion chamber pressure and extreme temperatures
• Accommodates cylinder head movement and thermal expansion
• Ideal for stock rebuilds, performance builds, and forced induction applications

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that maintains seal integrity under extreme conditions. The embossed layers provide multiple sealing points while allowing the gasket to adapt to minor surface imperfections. This design ensures consistent cylinder pressure and prevents coolant and oil leakage, making it an excellent choice for both street and performance Hemi builds.
