These are dual exhaust manifolds - Brand New. Had a project that never was completed and sold. I have these headers and want to offer up to other HAMB members before putting on fleabay. These are supposedly made of Ductile Iron ((has higher steel content) not cast iron. Easily weldable if the configuration needs to be modified. Made to fit 2 1/4" head pipes. These are currently raw metal and can be either painted or coated your call. A couple of known vehicle fitment issues: 62-67 Chevy ll Nova w/stick shift. The Z bar will need modified to clear the manifold 48-54 Chevy Truck w/230-250-292 possible fitment w/steering box and the from manifold. The manifold can be cut and welded to clear the steering.
