I dunno, I was generalising about studs with no particular location in mind.
Madmatt asked if they are welded in. All studs are held in location by threads, typically in a blind hole (eg. for the exhaust manifold), but sometimes in a through hole, so you can see the end of the stud on the rear face of a pipe flange for example. Some studs have two thread sections with a gap between to limit the insertion. Other types can have a different thread type at each end according to the metallergy of the parts being held.
