The major stresses on the case are carried by the case through bolts, which are calculated to act like a big enough spring to keep the bearing webs always in contact with each other. Not much of that stress gets applied to the smaller case studs.
While you gain no benefit by over torqueing these studs, neither are you apt to suffer any detriment operationally. Yes, you might keep an eye on them in case one shears and the nut and part of the stud goes AWOL. But I'd not worry about it. None of the studs broke, so none are likely to do so in the future.
I've always used thin steel washers for this application - the sealing capabilities of a crush washer really aren't needed. For valve covers, you really need the stronger aluminum sealing washers, because covers come off relatively often to check valve lash, and prying crushed ones off maybe doubles the time for the work.
Let the sealant cure and move on.

Yes, the voice of reason.
OP, worry about other stuff, you're fine.
