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 derby cover gasket 5-pack is designed for Panhead and Shovelhead V-twin motorcycles, providing multiple replacements for a leak-free outer primary. It's an OEM-replacement equivalent to part number 25416-70, ensuring a precise fit on classic Harley and Indian twins.

This Cometic 5-pack ensures you have plenty of quality replacements on hand for routine maintenance, primary inspections, or if you're building out multiple bikes. Each gasket is engineered to meet the demands of these vintage V-twin engines, delivering a dependable seal every time.

Good gasket, I like these because they are the same thickness as factory, and do not change the end play on the cam and breather

Decent gasket. Sticks out of the nosecone cover a bit at the top as it doesn't follow the nose cone shape precisely. Seals well.
