Product Details

The Cometic C5666-030 is a premium Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Ford 385 Series big block engines. This high-performance gasket features a 4.400-inch bore diameter and .030-inch compressed thickness, making it ideal for stock and mild performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.400-inch bore diameter accommodates standard and slightly overbored cylinders
  • .030-inch compressed thickness for optimal compression ratio
  • Engineered specifically for Ford 385 Series engines (429, 460)
  • Exceeds OEM specifications for performance and reliability
  • Provides excellent resistance to combustion pressure and thermal cycling

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a superior seal between the cylinder head and engine block. The embossed layers provide even load distribution and accommodate minor surface imperfections, while maintaining excellent torque retention and reusability.
