Product Details

The Cometic C5699-056 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-3 inline 6-cylinder engines. This high-performance gasket features a .056" compressed thickness and a 4.125" bore diameter, providing a precise seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • .056" compressed gasket thickness for optimal sealing
  • 4.125" bore diameter designed for Chevrolet Gen-3 inline 6 engines
  • Advanced material composition resists blowout and withstands extreme temperatures
  • Engineered to handle high-compression and forced-induction applications
  • Eliminates the need for retorquing after installation

Cometic MLS head gaskets utilize multiple layers of stainless steel with embossed sealing beads that create a superior seal around combustion chambers, coolant passages, and oil return holes. The gasket's ability to micro-conform to sealing surfaces makes it ideal for both street and race applications where reliability is critical.
