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 primary housing gasket is engineered for Evo Big Twin and Twin Cam V-twin engines, providing a reliable seal for the primary case. It's a direct replacement for factory gaskets, crucial for preventing leaks.
