Exhaust Stud Bolt Size?

[Jbrum]

Hey Guys. I was wondering does anyone know the size of the stud bolt for the exhaust to the header? I've seen countless threads about how to remove them but I think mine are bent because my exhaust(s) do not go on very easily at all. or is that normal? hahaha I have an 81 xs400sh I do believe. I have the part number but couldn't find it online to reference the size to get new ones. As Always you guys are awesome.
Thanks

Is there a torque setting at the collar for reinstallation?

I have never check the torque of the ones I have, but I would say enough to make them tight. Maybe 15-20lbs.
