Cometic C5512-057 MLS Cylinder Head Gasket 4.060" Bore Ford Windsor V8

Cometic C5512-057 MLS Cylinder Head Gasket for Ford Small Block Windsor V8

The Cometic C5512-057 is a premium multi-layer steel (MLS) cylinder head gasket designed for non-SVO round bore Ford Windsor V8 engines including 289, 302, and 351W applications. This gasket features a compressed thickness of 0.057 inches and a 4.060-inch bore diameter, making it ideal for performance builds and high-output engines.

Multi-Layer Steel Construction

This MLS head gasket is constructed from multiple layers of stainless steel, chosen for its superior strength, excellent rebound characteristics, and corrosion resistance. The outer embossed layers are coated on both sides with Viton (FKM)—a fluoroelastomer rubber material that maintains exceptional sealing performance at temperatures up to 482°F (250°C). The center shim layer consists of uncoated stainless steel and can be varied in thickness to achieve precise compression specifications.

Performance Features

• Load-Controlled Embossments: Promotes even clamp load distribution across the sealing surface, resulting in measurably reduced bore distortion
• No Sealants Required: Provides maximum sealing performance without the need for additional gasket sealers or compounds
• No Re-Torque Needed: The MLS design eliminates the need for re-torquing after initial installation
• Dual Material Compatibility: Excellent for aluminum-to-aluminum and aluminum-to-cast iron sealing applications, effectively handling the shearing forces created by dissimilar materials
• Chemical Resistance: Viton coating resists exposure to harsh sealing environments, various load conditions, and different surface finishes
