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 replacement for Panhead, Shovelhead, and Evolution Big Twin engines. It's designed to maintain a reliable seal across the demanding temperature and pressure cycles of classic V-twin powerplants. Sold in a convenient 5-pack, it's ideal for a full engine overhaul or multiple service jobs.

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?
