On a slightly different subject, I would definitely check to see if the bb shell needs to be faced on that old International, parallel shell faces are pretty critical with outboard bearing bb's. Having an early '70's International myself, if I were going to install outboard bb bearings in it, I'd be shocked if it didn't need a thorough facing to get the faces parallel with each other. . Also, FWIW, I'm not one to use a torque wrench too often, but on Hollowtech II crankset installations, I always use one on the crankarm pinch bolts.
