.990 torsion bars for 68 cuda.

hey autoxcuda, how will those 1.0" bars ride compare to the .990. seems there shouldn't be a huge difference. im debating wether i should get them or just stay with my .870 bars with my iron headed small block...whatchya think? i'm rebuilding the front suspension with RMS tubular a-arms and strut rods, firm feel 11/16" seemless tube tie rods, and factory iron disc brake kit, newer style spindles with bigger ball joints, and converting from power to manual steering. i will add a sway bar later, cuz the lower control arms dont have the provisions for one. but i would like to get heavier torsion bars. wut do you think of my setup?
