Engineered with Cometic's renowned Extreme Sealing Technology (EST), this comprehensive kit provides all the necessary components for a complete top-end overhaul, specifically designed for 1966-1984 Harley-Davidson Shovelhead engines.

Description

The Cometic Top End Gasket Kit offers superior sealing and durability, making it an essential choice for any Shovelhead engine rebuild. At its core is Cometic's advanced EST (Extreme Sealing Technology), featuring embossed stainless steel head, base, and rocker gaskets. These are meticulously covered with a proprietary rubber material, providing an exceptional seal that withstands the demanding conditions of a high-performance motorcycle engine. The specialized head gasket material is engineered to efficiently draw heat away from the combustion ring, distributing it evenly across the gasket surface. This crucial design element effectively eliminates problematic hot spots and significantly reduces the risk of gasket failure, ensuring long-term reliability for your 4-stroke 1200 cc, 1340 cc, or 1450 cc engine. This complete gasket set contains all the essential gaskets, seals, and O-rings required to rebuild your engine's top end, from the cylinder base upward, simplifying the overhaul process. Proudly Made in the USA, Cometic delivers uncompromising quality for your Harley-Davidson.
