Cometic .040" Head Gasket 2-Pack - Harley Twin Cam
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.

Designed as an OEM-replacement, these gaskets are essential for any engine rebuild or top-end service. They provide the sealing integrity needed to maintain optimal compression and prevent leaks on your V-twin.
