C9566 Cylinder head gaskets. .043" copper

If you need a thicker sealing option for your late Ironhead Sportster, these Cometic copper head gaskets are the answer. Measuring .043 inches in thickness, they are designed for late 1973 through 1985 XL1000 models. These gaskets replace OEM part number 16769-73 and are often used when cylinder or head surfaces have been machined, or when a builder wants to slightly lower compression. The copper construction ensures a high-strength seal that can withstand the pressures of the 1000cc Sportster engine. Cometic's reputation for quality means you can trust these gaskets to keep your vintage motor running leak-free.
