Product Details

The Cometic C5668-066 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford 385 Series big block engines. This precision gasket features a 4.670-inch bore diameter and a compressed thickness of .066 inches, providing exceptional sealing performance for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel construction for superior strength and reliability
  • 4.670" bore diameter optimized for Ford 385 Series engines
  • .066" compressed thickness for precise deck height management
  • Embossed steel layers with synthetic rubber coating ensure maximum sealing
  • Handles extreme cylinder pressures in boosted and high-compression applications
  • Superior rebound characteristics prevent gasket failure from thermal cycling
  • Compatible with Ford 429 and 460 cubic inch engines

Cometic MLS gaskets feature multiple layers of stainless steel with advanced coating technology that allows the gasket to conform to imperfections in the sealing surfaces. The stopper layer controls compression and protects against combustion leakage, making this gasket ideal for street performance, racing, and forced induction builds where reliability is critical.

Good prices on products. Response by email and phone.

Google searching produced this company as the lowest price on a set of spark plug wires. I like to deal with eBay, but I decided to try it out. Though the shipping was a bit more than Google estimated, it was still the lowest price! The item shipped quickly and was perfect with plenty of communication. Great seller!

ordered a steering box for a dodge truck, beat price i could find no hastle and easy to deal with i call and had a question and recieved an answer while on phone in just minutes.

Camaro Lug Nuts, They exactly what I wanted and they will fit like a glove, this I know because there are 5 of them on my car, so I ordered the same ones. very reasonable price. fast ship. All good, Thanks.
