Product Details

The Cometic C5711-098 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This gasket features a .098-inch compressed thickness and a 4.160-inch bore diameter, making it an excellent choice for stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • .098-inch (2.5mm) compressed gasket thickness
  • 4.160-inch bore diameter designed for Pontiac big-block V8 engines
  • Advanced embossment technology ensures even clamping pressure distribution
  • Stainless steel construction resists corrosion and withstands extreme temperatures
  • Accommodates deck surface imperfections better than conventional composite gaskets
  • Suitable for both naturally aspirated and forced induction applications

Cometic MLS gaskets are the preferred choice of engine builders and performance enthusiasts who demand reliable sealing under extreme combustion pressures. The multi-layer design allows for minor movement between the cylinder head and block while maintaining an effective seal, making these gaskets ideal for high-performance street engines and racing applications.
