Yes, the studs just screw into the manifold. Sometimes they're very stubborn, so use a good penetrating oil like KROIL or PB Blaster, some heat from a torch, and either a stud remover or tightly double-nut the studs and use a socket and a long handled ratchet or maybe an impact wrench to back them out. Dorman makes a good assortment of studs to choose from- - - -you'll probably find the thread in the manifold will be coarse, and the top will be a fine thread. For instance, 3/8-16 in the manifold, and 3/8-24 holding the carburetor on. Also try Fastenal for custom-length studs.
