Cometic H2570SPCN040S MLS Head Gasket 6-Bolt LSX .040" Right Side

The Cometic H2570SPCN040S is a Multi-Layer Steel (MLS) cylinder head gasket engineered for 6-bolt LSX performance engines. Designed for the right-side (passenger side) cylinder head, this gasket is built to deliver a reliable, high-performance seal on naturally aspirated, forced induction, and nitrous-fed applications.

Key Features:

• MLS Construction: Multiple layers of spring stainless steel provide superior strength and durability over traditional head gaskets
• Compressed Thickness: .040" — ideal for standard bore high-performance LSX builds
• Right-Side Orientation: Designed specifically for the passenger-side cylinder head on 6-bolt LSX engines
• Load-Controlled Embossments: Conform load distribution evenly across the sealing surface, reducing bore distortion
• FKM (Viton®) Rubber Coating: Applied to stainless steel outer layers for high-temperature and chemical resistance
• PTFE Topcoat: Provides added resistance to fretting and enhanced cold sealing
• No Sealant Required: Installs without additional sealants or re-torque when properly installed on prepared surfaces
• Made in the USA: Manufactured at Cometic's facility in Concord, Ohio

Cometic has been a leader in high-performance sealing solutions since 1989. The H2570SPCN040S is sold as a single gasket and is designed for use with properly machined head and block surfaces for optimal sealing performance.
