After installing rear blocks and aftermarket cranked torsion bars, do I need to get new shocks in the front, rear, or both. Also what does it do? Is it a comfort thing, I've heard that cranking torsion bars makes for a stiffer ride, so can new shocks make it a smoother ride?

 

If your shocks are worn I'd replace them, but its not neccessary after the lift you did. If you do replace the fronts use a stock length

No, different shocks won't make a difference in the ride stiffness and you don't need to replace them from cranking the torsion bars.

 

+1 no need to replace yours if you don't them
