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 rebuilding or upgrading your Harley Twin Cam, a quality head gasket is non-negotiable. This Cometic head gasket set for 4.060" bore V-twin engines comes in a two-pack, ready for your next project.
