You kind of have to feel your way through it don't you ? Hard to say being on the motor how much heat you can use if much at all to break any potentially seized bolts, if its just studs, as long as the threads are ok, can be chased, those just stay in place. The bolts if the heads are severely pitted, you know its bonded to the threads in the head or block, penetrating oil will mostly run off, now if'n you can turn the tractor on its side LOL !
I hate pondering this situation when you know you could deform the hex heads, easily snap one, only thing I learned with this is to take your time on each one, soon as you feel its going to round off, or really hard to turn, have to stop.
