What do you think?
I think you can drill the old stud and tap it for a 5/16" bolt. Slip a socket over the broken stud. Get a bolt/washer the appropriate length, grease the washer, run the bolt in the stud and jack it out.
If the stud shows a clean break, you probably had a bad stud. If the rocker arm cut a notch in it and that weakened it until it broke, you probably had either a cam going down or more likely a worn rocker nut that backed off and you continued to drive.
Inspect the top of the valve stem in the respective cylinders and make sure the top of the stem is square. If it isn't, you get to pull the head off and have the valve squared up.
