warped exhaust headpipe and broken manifold bolt on right side on 1997 Ford F-350

manifold bolt broken flush with manifold. headpipe warped and leaking exhaust from both places. 1990 motorhome with 460.

Asked by for the 1997 Ford F-350
the real way to do this is to remove the manifold and remove the bolts, re thread the holes and replace with new ones.
the manifold will have to go to a machine shop to be planed straight. add a new gasket.

very labor intensive. as a torch will be used often to remove rusted bolts.
