Take a close look at the studs, if they have rusted and are "thin" at the engine end they must be replaced unless you happen to like doing this job again later. If they are not rusted away, i.e. are full thickness, you can leave them alone but most folks would change them anyway.

Yours is not the usual case, typically people are dealing with original parts.
