Product Details

The Cometic C5804-070 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM Gen-1 and Gen-2 Ecotec L42 and L61 engines. This premium gasket features a compressed thickness of .070 inches and an 89mm bore diameter, making it ideal for stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .070" compressed thickness provides reliable head-to-block sealing
  • 89mm bore diameter designed for L42/L61 Ecotec engines
  • High-temperature resistance withstands extreme combustion pressures
  • Embossed stainless steel layers with elastomeric coating
  • Prevents coolant and oil leakage while maintaining proper compression

Cometic MLS gaskets are manufactured using multiple layers of stainless steel with specialized coatings that allow the gasket to adapt to block and head surface imperfections. This design ensures optimal sealing even under high-boost or high-compression conditions, making it a trusted choice for both OEM replacement and performance engine builds.
