Product Details

The Cometic C5846-080 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a precision 4.380-inch bore diameter and a compressed thickness of .080 inches, providing superior sealing performance for street and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and superior sealing
  • .080-inch compressed thickness provides optimal compression ratio control
  • 4.380-inch bore diameter designed for Pontiac 400/428/455 V8 engines
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Eliminates the need for additional sealants when properly installed
  • Ideal for both stock and high-performance engine builds

Cometic MLS gaskets feature multiple layers of stainless steel with advanced coating technology that allows the gasket to conform to surface imperfections while maintaining a reliable seal. This design makes them particularly well-suited for aluminum heads, high-compression applications, and engines with power adders like superchargers or turbochargers.
