Cometic C9583 Shovelhead 3-5/8" Big Bore Top End Gasket Kit

The Cometic C9583 is a premium top end gasket kit engineered specifically for big bore Harley-Davidson Shovelhead engines with a 3-5/8" (3.625") cylinder bore. This comprehensive kit includes head gaskets and base gaskets designed to handle the increased cylinder pressures and temperatures of big bore performance builds.

Key Features:

• Designed for 3-5/8" (3.625") big bore Shovelhead applications
• Includes cylinder head gaskets and base gaskets for complete top end sealing
• Multi-Layer Steel (MLS) head gasket construction for superior sealing and heat dissipation
• Premium materials engineered to handle high performance demands
• Manufactured in the USA with American-made materials
• Precision-engineered to exacting specifications for proper compression and leak-free operation

Cometic gaskets are constructed using advanced materials and manufacturing processes to provide reliable sealing in demanding performance applications. The MLS head gaskets draw heat away from the combustion ring and dissipate it evenly across the gasket surface to eliminate hot spots and prevent gasket failure. This kit provides professional-grade sealing components for builders who demand the best performance and reliability from their big bore Shovelhead engines.
