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.
For a complete engine gasket and seal replacement on your Twin Cam V-twin, the Cometic Twin Cam EST Gasket Kit provides everything required. This comprehensive set includes MLS head gaskets, steel Viton-coated base gaskets, and blue Viton valve stem seals, ensuring a reliable and leak-free rebuild. It's the all-in-one solution for your engine overhaul.

Works Fine at a lower cost
I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.

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?
