Cometic C9985-036 MLS Head Gasket 3-5/8 Inch Bore .040 Inch Thick

The Cometic C9985 is a multi-layer steel (MLS) cylinder head gasket featuring a 3-5/8 inch bore diameter and .040 inch thickness, designed for Harley-Davidson Shovelhead and Panhead engines. This gasket is sold as a pair, making it ideal for complete engine rebuilds or performance upgrades.

Advanced MLS Construction:

• Center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements
• Outer layers are embossed and coated on both sides with Viton to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes
• MLS head gaskets promote an even torque load across the gasket sealing surface utilizing LCE (Load Control Embossments), providing less bore distortion and better piston ring seal for more power
• Multi-layer stainless steel construction creates the ability to rebound and resist corrosion

These head gaskets are ideal for aluminum heads, aluminum blocks, and cast iron blocks. Made in the U.S.A. Cometic gaskets are trusted by professionals in high-performance applications and as OE replacements worldwide.
