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.
Cometic Milwaukee-Eight 0.014" Gen2 Embossing Base Gasket - Harley & Indian V-Twin
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.
When rebuilding your Milwaukee-Eight engine, a reliable base gasket is crucial for maintaining cylinder integrity and preventing leaks. Cometic's .014" Gen2 Embossing base gasket is engineered specifically for M8 powerplants, offering advanced sealing technology.
