I am in search of an exhaust manifold for the passenger side of a 400,430.455 in which the rear port exits down or forward instead of going to the rear before it drops down. Is their such an animal or am I going to have to build a set of headers for the car. This engie is in a '33 Buick sedan. The best option would be a mirror image of the drivers side manifold for the right side. Please, any help or advice is really needed.
