Product Details

The Cometic C5769-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a 4.200-inch bore diameter and a compressed thickness of .070 inches, providing reliable sealing for stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.200-inch bore diameter optimized for Pontiac V8 applications
  • .070-inch compressed gasket thickness
  • Accommodates thermal expansion and cylinder head movement
  • Resists combustion pressure and maintains consistent seal
  • Compatible with Pontiac 400, 428, and 455 V8 engines

Cometic's MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that can withstand extreme cylinder pressures and temperatures. The embossed layers provide multiple sealing points while maintaining the flexibility needed to adapt to imperfect sealing surfaces. This design makes the C5769-070 an excellent choice for street performance, racing, and engine rebuilds where reliability is critical.
