Product Details

The Cometic C5769-120 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 .120 inches, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • .120-inch (120 thousandths) compressed gasket thickness allows for precise compression ratio tuning
  • 4.200-inch bore diameter optimized for Pontiac 400/428/455 V8 engines
  • Stainless steel construction with Viton rubber sealing beads resists blowout and maintains seal integrity
  • Accommodates thermal expansion and contraction better than composite gaskets
  • Suitable for high-performance, turbocharged, supercharged, and nitrous applications

Cometic MLS gaskets are the choice of professional engine builders and performance enthusiasts who demand maximum reliability. The multi-layer design allows the gasket to recover and maintain torque loads better than conventional gaskets, while the embossed stainless steel layers provide excellent conformability to deck surface irregularities.

shipping charge ruined this experience...

Your website is easy to work thru.

Very pleasant.

It was a good price with fast delivery. They had the lowest price I found. My only comment was the shipping cost was more then I expected.

I was able to find a part I couldn't find anywhere else, and at a reasonable price! Thank you!
