The 10mm Allan bolt are always a sod to get out!! Regardless of how long they been in there an how tight they were done!

I did a clutch on gtiteen car a few weeks later the box went bang I snapped my snap on 10mm 3/8 drive Allan key trying to undo the pivot plug to witch I defo didn't do that tight!!!
I always use plenty of lube on the pivot arm/pin and on the thread of the bung.

Top bell housing bolts always seem to pick up, there was a time I was doing 3/4 clutchs/boxes a week at least 1 that we to have issues with, I spose you must be very lucky if you've never had issuses before!
