Product Details

The Cometic C5400-092 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This gasket features a 4.125-inch bore diameter and a compressed thickness of .092 inches, making it ideal for performance builds and engine rebuilds.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
  • 4.125-inch bore diameter accommodates standard and slightly modified cylinder bores
  • .092-inch compressed thickness allows for precise compression ratio tuning
  • Undersized water ports enable custom machining and porting to match specific aftermarket cylinder heads
  • Designed for use with aftermarket performance heads on Gen-1 Small Block Chevy applications
  • MLS technology features multiple layers of stainless steel with elastomeric coatings for maximum combustion sealing

This gasket is compatible with Chevrolet Gen-1 Small Block V8 engines (262-400 cubic inch displacements) when paired with aftermarket cylinder heads. The undersized water ports provide flexibility for engine builders to custom-fit the gasket to their specific head and block combination, ensuring optimal coolant flow and sealing performance in high-performance applications.
