i have a couple of questions
I doubt the head or main bolts are hurt much, the block wont have suffered any significant damage. if it did it would have ripped the threads out of the block. I'd replace the bolts anyway.
Are you certain the torque reading is off that much for the rod bolts ? Remember its a lower torque reading. check them with your reference. You might find they arent that over torqued.
The kicker are the rod bolts. In order to replace them you need to install (press them in) when you press them - the big end distorts to some degree and thus changes the roundness of the bearing cavity. This means the heads have to come off the pistons and rods out as well, and be sent to the shop for the bolt replacement and checking for out of round, you might get lucky and have no change in out of round. Sorry for the bad news.
