Cometic Cylinder Head Seal (1-Pack) - Harley Evolution & 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.
Ensure optimal cylinder head sealing with this Cometic seal, designed for both Harley Evolution and Twin Cam V-twin engines. This OEM-equivalent replacement helps maintain engine performance by preventing leaks at the cylinder head.
