Try looking for your headers under the Javelin or AMX models. With the 401 you will need the "dog leg" type of headers. Edelbrock makes them both for the long tube and short(y) tube headers available in both the cermanic and chrome type headers.I am assuming that you have an American and the interior engine bays and floor pans are the same as the Javelin with the
AMX being the same until just to rear of the front passenger seats. AMC did this to save cost on tooling and the such.
