Cometic H1330SP8051S MLS Cylinder Head Gasket Bore - 80mm 051in

The Cometic H1330SP8051S is a Multi-Layer Steel (MLS) cylinder head gasket featuring an 80mm bore and .051-inch compressed thickness. Engineered for high-performance powersport and sport compact applications, this gasket delivers a superior combustion seal where a stock gasket simply cannot hold up to increased power levels.

Key Features:

• Multi-Layer Steel (MLS) Construction — Multiple embossed layers of proprietary high-temperature coated and uncoated stainless steel provide exceptional strength and durability
• 80mm Bore Diameter — Precise bore sizing maintains optimal compression and combustion chamber integrity
• .051-Inch Compressed Thickness — Allows precise compression ratio tuning for performance builds
• Load-Controlled Embossments — Conform load distribution across the sealing surface, requiring less clamp load and creating less bore distortion
• Viton Rubber Coating — Outer stainless steel layers feature a .001-inch Viton rubber coating bonded to the surface for a micro-seal against fluids
• No Sealants Required — Installs dry; additional sealants are not needed and can hinder performance
• No Re-Torque Required — When installed on properly prepared surfaces (50 RA or finer surface finish recommended)
• Made in the USA — Manufactured at Cometic's state-of-the-art facility in Concord, Ohio

Cometic MLS head gaskets are the preferred choice for engine builders demanding a reliable, race-proven seal in performance street and competition applications. The active combustion seal on multiple layers ensures consistent sealing integrity under extreme cylinder pressure and temperature cycles.
