340/mag360 exhaust manifolds

no, I defiantly need middle dump, one thing you dont see in the pic, is the z bar and linkage as I am running a a833 plus I tried mounting the 80 Dodge truck manifold and it wont fit even if I remove the rear stud and replace with a bolt, I guess I may have to use center dump headers? or stick with the 69 318 one but I just dont like the 1 3/4 outlet, too small.
