Product Details

The Cometic C5769-056 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a compressed thickness of .056 inches and a 4.200-inch bore diameter, providing an optimal seal for both stock and high-performance applications.

Key Features:

  • Multi-Layer Steel construction for superior strength and durability
  • .056-inch compressed thickness for precise compression ratio tuning
  • 4.200-inch bore diameter designed for Pontiac V8 engines
  • Multiple layers of stainless steel with elastomeric coating for exceptional sealing
  • Resists blowout and withstands extreme cylinder pressures
  • Ideal for turbocharged, supercharged, and naturally aspirated engines
  • No retorquing required after installation

Cometic MLS gaskets are manufactured using advanced materials and precision engineering to deliver race-proven performance and reliability. The multi-layer design allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface, making it an excellent choice for both street and racing applications.
