401 exhaust manifolds

I can't help you, I used the last set I had on my Rambler. All AMC V-8 exhaust manifolds are the same for 304-401, car and truck, from 72-85 or so. After that they changed the driver side, but the passenger side is the same to 91. Some early ones (up to 74 I think) were not drilled for air tubes. They are available in the aftermarket from Omix-Ada. Patriot exhaust also has an H8600 shorty header that is a direct bolt in for the factory exhaust manifold.
