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 Intake/Exhaust Gasket .031" - Harley & Indian M8
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.
Ensure a perfect seal on your Milwaukee-Eight's intake and exhaust manifolds with this Cometic OEM-spec gasket. Designed for direct fitment on Harley-Davidson and Indian Motorcycle M8 engines, this .031" gasket provides reliable, leak-free performance. A fresh gasket is critical for optimal engine operation and preventing exhaust leaks.
