If you have not hightened down the head already, the gasket can be reused "if not torqued"
I would pull the head, put two nuts on top threds lock the nuts screw the studs back in. you do not what too rick pulling the threads in the crank case.

does it sound like it could be a problem with the stud because everything was put in that was taken out head an base gasket so it isn't like we forgot something

If all the washers are on and the studs were screwed all the why in the only thing it could be is bolt strech. put two washers on. if the bolt don't brake your all set.

Get all four. they are around 8.00 each.
you need two 10x156 #80925-001
and two 10x166 #81004-001
If one is bad the others are close
They make good spares ,just incase.

at least one full tank. drive it around for 5-10min at a time & let it cool off completely in between. never ride at a steady rpm. don't use full throttle (opinions vary on that).
