It all depends on how you are going to drive the car. If it is a show poodle then who cares, the torsion bars just hold it up in the air. If you are actually going to unleash the Hemi once in a while then now would be a good time to upgrade the suspension and brakes. If it was me I'd put larger than stock torsion bars on there as well as disc brakes and high quality shocks. But if you're just going to cruise over to the burger joint on Saturday night then save your money and use it on some chrome valve covers.
