I would think that the effect of the stripped manifold stud on the running of the engine would be related to a loose intake manifold, i.e. sucking air, and not so much the effect of the loose exhaust manifold (other than added exhaust noise which sometimes is mistaken as an engine tapping sound). Careful drilling, tapping, insertion of the correct helicoil and new stud should solve the problem. If done with the engine in the car the challenge will be to get the drill to run straight and true into the block.
