About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
This Cometic seal is a direct OEM replacement for Panhead, Shovelhead, and Evolution big twin engines. Supplied in a convenient 5-pack, these seals are engineered to prevent oil weeping at critical engine sealing points across various classic Harley-Davidson platforms.
Why riders pick this

- Reliable sealing for classic Harley-Davidson V-twins
Whether you're restoring a classic Panhead or maintaining a dependable Evo Big Twin, reliable sealing is paramount. These Cometic seals are manufactured to match OEM specifications, providing the crucial barrier needed to keep your engine cases dry and functioning correctly. A small leak can quickly become a big problem, making quality seals an essential component of any engine work.

A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
