You are probably back at original ride height as they had a forward rake to them new, I wouldn't expect it to come down much. If you torqued the bolts when the car was in the air you may have binding. Try loosening the F/R leaf bolts and bouncing the car up and down, then tighten them up again, see if that helps.
The originals are standard eye, 1" lowering are mideye and 2" drop are reverse eye. Standard puts your fender lip 1-2" above the tire tread normally (15" tire), mideye puts you almost level with the tire tread and reverse puts the tire into the fender well. This varies slightly by car just becaus they're not exact and tire size (height) will have an effect also, just general parameters.
I put mideye 4 1/2 leaf on my '67 and it's perfect for me, not too stiff but tighter, no bottoming or pounding on dips/potholes and the height is right where I want it. I have read some who went 5 leaf and didn't like the stiff ride but that's subjective, too stiff for me might be fine for them but I think that's where the line is, between 4 1/2 and 5 leaf. Same for shocks, I have KYB GR-2's which are fine for now, ride nice but probably not good enough for open track, for <$100/4 they'll do. I have read many who used the KYB gas-a-justs and took them off due to jarring ride on rough road surface. I'm also running 1" drop 550 springs in front w/arning drop and like that also, car sits level.
