Product Details

The Cometic C5256-030 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet 348 and 409 cubic inch W-Series Big Block V8 engines. This high-performance gasket features a .030" compressed thickness and 4.375" bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • .030" compressed thickness allows for precise compression ratio tuning
  • 4.375" bore diameter accommodates standard and mild overbore applications
  • Engineered specifically for Chevrolet W-Series Big Block architecture
  • Exceeds OEM specifications for reliability and performance

Cometic's MLS gaskets utilize multiple layers of stainless steel with elastomeric coatings to create a gasket that can withstand extreme cylinder pressures and temperatures. The embossed layers provide multiple sealing points while allowing the gasket to move with the engine's thermal expansion and contraction. This design makes the C5256-030 an excellent choice for street performance, restoration, and mild racing applications on classic Chevrolet W-Series engines found in 1958-1965 full-size Chevrolet vehicles.
