Product Details

The Cometic C5256-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet 348 and 409 cubic inch W-Series big block V8 engines. This precision-manufactured gasket features a .045-inch compressed thickness and a 4.375-inch bore diameter to provide optimal sealing and combustion chamber sealing.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .045-inch (1.14mm) compressed gasket thickness
  • 4.375-inch bore diameter designed for 348/409 W-Series engines
  • Embossed stainless steel layers with viton rubber sealing beads
  • Handles extreme cylinder pressures in high-performance and racing applications
  • Superior resistance to blow-out compared to composite gaskets
  • Reusable design allows for multiple installations when properly maintained

Cometic MLS head gaskets are the professional choice for engine builders working with vintage Chevrolet W-Series big blocks. The multi-layer steel construction conforms to irregular sealing surfaces while maintaining excellent recovery properties, making them ideal for engines with increased compression ratios, forced induction, or nitrous oxide systems.
