5 stars! fit perfect! snug enough to hold its self in place while installing exhaust, but not so tight as to cause gasket damage when inserting into place.

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.

Engineered to prevent oil seepage, these gaskets are a must-have for any rider or shop performing regular maintenance on classic V-twin engines.

Common questions
Why should I buy a 5-pack of these gaskets?
A 5-pack is ideal for riders who frequently service their Evo Big Twin or for shops that need to keep spares on hand. It ensures you always have a fresh gasket ready, as replacing it with each removal is best practice to prevent leaks.
