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 top-end rebuild on your Evolution Sportster, trust the Cometic head and base gasket kit. Engineered to OEM specifications, this kit provides reliable sealing for your V-twin engine's cylinders.
