First of all, return the nuts to the same rod bolt as they were removed from. After that, I can only tell you what I've done - if it only took a very small amount (2-3 ft.-lbs) of under torqueing to reach the cotter pin location, I've done that. I don't overtorque. When that wasn't an option I removed the nut and dressed the flat on a piece of emery cloth glued to a piece of flat glass until I had removed enough to get an alignment. Don't forget to clean thoroughly before installing again.

PS - just checking the rod bearing cap torque specs in Motor's Manual I see an interesting anomoly; for the 46 Super 8 engine they show 56-58 ft-lbs, but for the 47 Super 8 (same engine) they show 60-65 ft-lbs. so perhaps you have a little more leeway to tighten. Motor's shows the same specs for the main bearing caps, 82-85 ft.-lbs. I didn't check to see what the Packard specs were.
