I remember only John's mods to Kato short turnouts, not Atlas #10s.
I agree with Chris: with Atlas turnouts the more you mess with them the more you mess them up.
Like he said, a dab of silcone under the hinged pivots might help keep the point rail sections in, but unless you find that they're popping out before you install them then they probably won't pop out later.
If some of your locos / cars are bumping up & down a little through the frog, then take a triangle file & make a FEW passes along the spikes on the inside of the rails between the hinge and the frog:
On the old run those sometimes sat a little proud.
Or, swap out your wheels for low-pro.
Otherwise, the only "mod" you should be making is powering your frogs
