Product Details

The Cometic C5400-045 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines. This precision gasket features a .045-inch compressed thickness and a 4.125-inch bore diameter, making it ideal for high-performance and racing applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under extreme pressures
  • 4.125-inch bore diameter accommodates stock and slightly modified cylinder bores
  • .045-inch compressed thickness allows for precise compression ratio tuning
  • Undersized water ports designed for aftermarket cylinder heads, allowing custom porting and coolant flow optimization
  • Compatible with Gen-1 Small Block Chevy engines (265, 283, 302, 327, 350, 400)
  • Embossed stainless steel construction with Viton rubber sealing beads

Cometic MLS gaskets are the preferred choice for engine builders who demand maximum reliability in boosted, nitrous, and naturally aspirated high-compression applications. The undersized water ports give you the flexibility to match-port your cooling passages for aftermarket heads, ensuring optimal coolant flow without restriction.
