Product Details

The Cometic C5769-092 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This precision-manufactured gasket features a 4.200-inch bore diameter and a compressed thickness of .092 inches, providing an excellent balance of sealing performance and compression ratio control.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.200-inch bore diameter designed for Pontiac V8 applications
  • .092-inch compressed thickness for optimal sealing and compression management
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Accommodates minor surface imperfections for reliable sealing
  • Ideal for both stock rebuilds and high-performance applications

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that responds to flange movement and extreme cylinder pressures. This design makes them an excellent choice for performance Pontiac builds, forced induction applications, and engines running higher compression ratios. The .092-inch thickness allows engine builders to fine-tune compression ratios while maintaining excellent combustion sealing.

Quick and simple buying experience

Great service

delivery was fast and everything went well

Fantastic

Easy to purchase. Fast shipping.

I was surprised to find marine rated electrical items at Autoplicity, but they had what I needed and at a good price. Will be shopping at Autoplicity again.

Not bad. Great prices. Only problem is. When item is placed in cart it rushes to checkout. Had to keep going back to find other items I needed
