Product Details

The Cometic C5274-045 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines equipped with Edelbrock RPM cylinder heads. This precision gasket features a 4.135-inch bore diameter and .045-inch compressed thickness, providing optimal sealing for high-performance applications.

Key Features:

  • Multi-Layer Steel construction for superior sealing and durability
  • 4.135-inch bore diameter accommodates stroker and overbored applications
  • .045-inch compressed thickness allows for precise compression ratio tuning
  • Specifically designed for use with Edelbrock RPM cylinder heads
  • Compatible with Chevrolet Gen-1 Small Block V8 engines (265, 283, 302, 327, 350, 400 cubic inch)
  • Eliminates the need for retorquing after initial installation

Cometic MLS gaskets utilize multiple layers of stainless steel with a Viton rubber coating to maximize sealing performance under extreme cylinder pressures and temperatures. The steel construction allows the gasket to rebound and maintain seal integrity through repeated heat cycles, making it ideal for naturally aspirated, supercharged, and turbocharged applications. This gasket is designed for performance engines and requires proper surface preparation (30 RA or smoother finish recommended) for optimal results.
