I usually just buy new studs and nuts and copper-antiseize them before assembly, sorry I can't remember the size.

I did my cherokee a year ago, cant remember if you could knock the out or if their welded, but any auto part store that carries the stud for the manifold can tell you the thread size.

I just did my manifold gaskets. IIRC they were 9/16" but there are 2 different threads on it. Just reuse the old stud and bolt, thats what I did with no problems.
