The arm still has to come down. You are saying that it isn't.
If the bumper is correct, that's fine... If it's not hitting... Then you haven't pulled the arm down to meet the spindle. If the arm doesn't pull down, then something is wrong.
If it's stiff because of new bushings, then loosen the bolts and tighten after it's together, (which I'll make an argument should be done anyway, but some will disagree that it's not necessary).
As I said, I don't loosen the torsion bars, but it has been recommended by many, especially because you are new at this, and I agree that it will help pull the LCA up, but the UCA still has to come down to meet it...
Let's also ask this question... What else did you change? I can't see if the lower ball joint has been changed and usually those are what wear and the uppers don't (as much). Obviously, the lower control arm bushings weren't changed (never touched the torsion bars) , another spot that wears before the upper bushings.
You've still got to address the upper ball joint anyway... Buy the right socket and see if it tightens (I bet it won't) and either replace the UCA or a couple welds to hold the new one in place.
