If that’s the case, you probably want to go the drop spindles route. I’m generally not a fan of them but I build my cars for autoX and handling, and doing that means larger bars anyway so the drop spindles become unnecessary to lower the car. You can correct the added bump steer other ways.
If turning the wheel actually causes the headers to rattle against the torsion bar, you may also want to look at your engine mounts, steering box and K frame. Because turning the wheels shouldn’t change anything as far as header to torsion bar clearance unless something is moving that isn’t supposed to move when your turn the wheels.
