One set of 6.1L multi-layer steel exhaust manifold (header) gaskets. These are OEM stock replacements but also can be used with aftermarket performance headers such as JBA, Kooks, Dynatech and Gibson headers.

If you need to replace your header gaskets, we recommend using these. This kit consists of the following: 1 Passenger Side 6.1L Header Gasket 1 Driver Side 6.1L Header Gasket
