Suspension Review
I can't say if you will find the 1"+ bars to be too stiff or not, but make sure to give a good careful inspection to the rear torsion bar crossmember. It is much easier to beef it up before it breaks than it is to fix it after it is broken. The rear crossmember is a known problem area and were frequently improperly welded at the factory. Sounds like a gunshot when the mount lets go and it no fun to repair.
