This precision gasket features a 4.275-inch bore diameter and .063-inch compressed thickness, utilizing Cometic's advanced DST (Diesel Stopper Technology) multi-layer steel construction.

Key Features:

• Multi-layer steel (MLS) construction with DST technology for superior sealing and durability
• 4.275-inch bore diameter optimized for Dart Hemi Gen3 Iron Eagle blocks
• .063-inch compressed thickness for precise compression ratio tuning
• Application-specific design for RHS (Race Head Service) cylinder heads
• Viton rubber gasket material around combustion chamber and oil passages for maximum sealing
• Stainless steel construction resists corrosion and withstands extreme temperatures
• Embossed combustion chamber sealing beads for enhanced seal integrity

Cometic MLS head gaskets feature multiple layers of stainless steel with an embossed active sealing area that responds to the flanges and combustion pressures to create a superior seal. The outer layers are coated with a rubber-based material that provides micro-sealing properties at the head and block surfaces. This gasket is ideal for high-performance street and racing applications where reliable sealing under extreme conditions is critical.
