I use a stud and 15/16? nut kit that Callie?s sells. The large nut has a bunch of surface area to grip on the balancer. Never had an issue and it?s very nice having a stud and nut for the snoot threads rather than a bolt.
And yes, big springs do make it harder unless you have roller cam bearings, because the cam is down hard on the Babbitt with no hydrodynamic wedge yet while just turning by hand.
