Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.

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 molded rubber primary gasket offers a superior seal, designed to withstand the demands of your V-twin engine. It's a direct replacement for the stock part, ensuring a precise fit and reliable performance.

Common questions
Is this gasket compatible with my Milwaukee-Eight Softail?
