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.
When it's time for a full engine overhaul on your Harley-Davidson Twin Cam, this Cometic EST gasket kit provides all the essential components for a thorough and reliable rebuild. It includes high-quality MLS head gaskets, durable steel Viton-coated base gaskets, blue Viton valve stem seals, and various AFM material components, ensuring a complete and leak-free engine assembly.

Works Fine at a lower cost

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?
