Tire shop over torqued lug nuts (1969 Dart). Should I redo it?

Beams are fine and quite accurite. Not handy for lug nots but it will work fine.
Thanks. Yeah, it had to bend and twist into some less than comfortable positions to read the gauge on the beam wrench, while applying 55 ft lbs of force. But it was a good workout.

Is it okay to use the beam wrench like a breaker bar, as I was doing? I know they say not to do this with clicker style torque wrenches. But I couldn't really see why it mattered with the beam style wrench. And it allowed me to measure the torque it took to get the lug nuts to loosen.
