Product Details

The Cometic C5667-140 is a high-performance multi-layer steel (MLS) cylinder head gasket engineered specifically for Ford 385 Series engines. This precision-manufactured gasket features a 4.500-inch bore diameter and a compressed thickness of .140 inches, making it ideal for both stock rebuilds and high-performance applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under extreme cylinder pressures
  • 4.500-inch bore diameter designed for Ford 385 Series big block engines (429, 460 variants)
  • .140-inch (3.56mm) compressed gasket thickness for precise compression ratio tuning
  • Embossed stainless steel layers with Viton rubber coating ensure maximum sealing capability
  • Resistant to high temperatures and combustion pressures in performance applications
  • Allows for minor surface imperfections while maintaining proper seal integrity

Cometic MLS gaskets are a premium choice for engine builders who demand reliability in street performance, racing, and forced induction applications. The multi-layer design allows the gasket to adapt to thermal expansion and contraction, maintaining a consistent seal throughout the engine's operating range.
