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 Twin Cam carb/EFI gasket is engineered for a precise seal on your V-twin's intake or fuel system. Sold in a convenient 10-pack, it's an ideal choice for shops, multi-bike owners, or riders who prefer to keep spares on hand for routine maintenance. Designed as a direct OEM replacement, these gaskets help prevent leaks and maintain peak engine performance.

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?
