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 base gasket for Panhead and Shovelhead engines is sold in a convenient 2-pack, perfect for engine rebuilds or multi-bike service. Crafted from factory-engineered gasket material, it's designed to handle the compression and heat cycles of classic V-twin bottom ends.
