Product Details

The Cometic C5712-036 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 4.300-inch bore diameter and a compressed thickness of .036 inches, making it ideal for performance builds and engine rebuilds requiring precise sealing and durability.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • .036-inch compressed gasket thickness for optimal compression ratio tuning
  • 4.300-inch bore diameter designed for Pontiac big-block V8 applications
  • Embossed stainless steel layers with elastomeric coating ensure maximum conformability to head and block surfaces
  • Excellent resistance to blowout and combustion leakage in high-performance applications
  • Reusable in many applications when properly installed and removed

Cometic MLS gaskets are a premium choice for engine builders and enthusiasts who demand reliable sealing in street performance, racing, and forced induction applications. The multi-layer design allows the gasket to adapt to thermal expansion and contraction while maintaining consistent clamping force across the entire sealing surface.
