Product Details

The Cometic C5739-056 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet 4.3L Generation 1 90-degree V6 engines. This precision-manufactured gasket features a .056" compressed thickness and is designed for a 4.060" bore diameter, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-layer steel construction for superior sealing and durability
  • .056" (1.42mm) compressed gasket thickness
  • 4.060" bore diameter for precise fitment
  • Designed for Chevrolet 4.3L Gen-1 90-degree V6 engines
  • High-temperature resistant materials withstand extreme combustion pressures
  • Engineered to handle thermal expansion and contraction cycles

Cometic's MLS gaskets utilize multiple layers of stainless steel with advanced coating technologies to create a reliable, reusable seal. The gasket's design accommodates minor surface imperfections while maintaining excellent resistance to blowout and coolant leakage. Ideal for stock rebuilds, performance applications, and forced induction setups where a proven, high-quality head gasket is essential.
