Product Details

The Cometic C5846-030 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a .030" compressed thickness and is manufactured to accommodate a 4.380" bore diameter, making it ideal for stock and performance builds.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • .030" compressed gasket thickness for precise deck height management
  • 4.380" bore diameter designed for Pontiac V8 applications
  • Embossed stainless steel layers with advanced coating technology
  • Exceeds OEM specifications for high-performance and racing applications
  • Resists corrosion, temperature extremes, and combustion pressure

Cometic MLS head gaskets use multiple layers of stainless steel with polymer micro-bead coatings to create a superior seal between the cylinder head and engine block. The gasket's design allows for thermal expansion and contraction while maintaining consistent clamping pressure across the entire sealing surface. This makes the C5846-030 an excellent choice for street performance, racing, and engine rebuild applications on classic Pontiac V8 engines.
