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 engine seal is engineered as a direct OEM replacement for Panhead, Shovelhead, and Evolution Big Twin engines. It's sold in a practical 5-pack, making it an excellent choice for shops, multi-bike owners, or riders who prefer to have spares on hand. This seal is crucial for maintaining the integrity of your V-twin powerplant.

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?
