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.
Maintain a secure primary on your V-twin with this Cometic primary gasket. Designed to OEM-replacement specifications, it provides a reliable, leak-free seal for Panhead, Shovelhead, and Evo Big Twin engines on Harley-Davidson and Indian motorcycles.

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?
