Product Details

The Cometic C5331-057 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Mark IV Big Block V8 engines with a 4.630" bore diameter. This precision-engineered gasket features a .057" compressed thickness, making it ideal for performance builds requiring precise deck height adjustments and reliable sealing under extreme conditions.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .057" (1.45mm) compressed gasket thickness for precise compression ratio tuning
  • 4.630" bore diameter designed for Big Block Chevy Mark IV engines (396, 402, 427, 454, 502)
  • Engineered to withstand high cylinder pressures and extreme temperatures
  • Accommodates engine movement and thermal expansion for leak-free performance
  • Ideal for performance, racing, and high-boost applications

Cometic's MLS gaskets feature multiple layers of stainless steel with a viton rubber coating that provides exceptional recovery and sealing characteristics. This design allows the gasket to maintain its integrity through repeated heat cycles while conforming to minor surface imperfections on both the block and cylinder head.
