Beveling the ends of the outside torsion leaves does, in fact, make it slightly easier to insert them into the torsion tube center donut and/or the trailing arm, but I’ve assembled a LOT of front ends and never bothered to do that.
What does work well is to stack up the leaves and put a rubber band around them a couple of inches from the end. Insert the leaf stack into the center donut (jiggling around helps), rubber band and all. It will just push to the entry side of the donut and sit there forever, or until someone in the year 2027 takes it apart and wonders why the hell there is a rubber band on the torsion bar. Last couple of times I built a front end I used the rubber band from a bunch of Broccoli and it worked fine.
Recycle whenever you can!
On the grease thing, you wrote, “I guess my better question would be, is there a way to repack and seal them. Or should I simply wipe them off and live with it? ”
They are working as designed. They are supposed to leak like that. That’s how they were designed in 1946. Wipe them off and live with it.
BTW, 6,000 miles between front end greasing sounds wonkey on these cars. Once a year, as part of Spring maintenence, sounds about right, UNLESS you have a pair of Urethane torsion bar bushings (it appears that you don’t). Those are more involved to grease, unless you’ve drilled them for a grease passage and fitting.
