Product Details

The Cometic C5666-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford 385 Series big block engines. This precision gasket features a 4.400-inch bore diameter and .045-inch compressed thickness, making it ideal for performance builds and engine rebuilds requiring reliable sealing under extreme conditions.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .045-inch compressed gasket thickness
  • 4.400-inch bore diameter optimized for Ford 385 Series engines
  • Engineered to withstand high cylinder pressures and temperatures
  • Provides excellent resistance to combustion gas leakage
  • Accommodates thermal expansion and head lift in performance applications

Cometic MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to create a reliable seal between the cylinder head and engine block. The flexible design compensates for minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface. This gasket is compatible with Ford 385 Series engines including 429 and 460 cubic inch variants.
