Product Details

The Cometic C5432-040 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines. This high-performance gasket features a .040" compressed thickness and is designed for a 4.310" bore diameter, making it ideal for custom engine builds and performance applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under high combustion pressures
  • 4.310" bore diameter accommodates stroker builds and overbored cylinders
  • .040" compressed thickness allows for precise compression ratio tuning
  • Undersized water ports enable custom machining and port matching to optimize coolant flow
  • Designed for aftermarket cylinder heads with non-standard port configurations
  • Embossed stainless steel layers with an FKM (fluoroelastomer) coating for maximum sealing

Cometic MLS gaskets are the preferred choice of professional engine builders and racing teams for their ability to withstand extreme temperatures and pressures while maintaining a consistent seal. The undersized water ports give you the flexibility to custom-tailor the gasket to your specific cylinder head and block combination, ensuring optimal cooling performance in high-output applications.
