As an aside, when working on old bikes, sometimes a torque wrench isn't the best tool to use. Ironically, just using a ring spanner and finger tight FEEL of the bolt can tell you if the threads are going to pull out or if there is resistance when tightening.
Had to helicoil far too many camshaft cap bolts because they'd been overtightened and pulled the alloy threads out of the head. Not fun.
If I owned this bike, I would replace all the camshaft cap bolts as a precaution.
