Product Details

The Cometic C5769-051 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This high-performance gasket features a 4.200-inch bore diameter and a compressed thickness of .051 inches, providing an excellent balance of sealing capability and compression optimization.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .051-inch compressed gasket thickness for precise compression control
  • 4.200-inch bore diameter designed for Pontiac big-block V8 engines
  • Application-specific design for 400, 428, and 455 cubic inch Pontiac engines
  • Embossed stainless steel layers with advanced coating technology
  • Excellent resistance to extreme temperatures and combustion pressures
  • Provides consistent clamping pressure across entire sealing surface

Cometic MLS gaskets utilize multiple layers of stainless steel with precision-engineered embossments that allow the gasket to conform to sealing surfaces while maintaining structural integrity. This design is ideal for performance builds, forced induction applications, and high-compression naturally aspirated engines where reliable head sealing is critical.
