Future suspension setup?

66 valiant 2 door post, slant6 with work, front sbp disc conversion,205 - 15 front/215 - 15 rear. Looking for a good handling all around street driver setup. This is what I come up with:
Bilstein rca all around
Offset uca bushings,(was thinking of qa1 tubular upper arms but not sure it's worth the extra cost for my setup)
Greasable pivot shafts with poly bushings
Adjustable strut rods (qa1's)
Torsion bars 1.03 (pst)
Rear poly kit
Rear springs 103 rate , not sure of a good brand to go with Mancini/espo/afco/ hotchkiss/general
Will weld up lower arms,k frame, frame connectors.
Any suggestions or changes?
Thanks
Ps. Also adding a bergson power steering kit, may increase tire width in the future
If this is to remain a slant 6 street car, a lot of your list is overkill IMO. I'd keep it mostly stock with a few exceptions. I'd for sure add a front sway bar and up the torsion bar diameter, although maybe not quite that much. Good set of shocks......sure, but tubular control arms, welding the lowers, adjustable strut rods......no. Same goes with the frame connectors, not needed on a slant 6 street car. Stock 6 leaf rear springs and maybe a small diameter rear bar and call it a day.
