SS Springs

I have Mopar SS springs (2800LBS) on my Dart. There are different P/Ns for the left and right spring and the only difference I can see is that the bottom leaf (really just a half leave) is pointed in different directions. One points to the front, the other one points to the rear.

My questions why, and if I point them both to the front, will my car sit more level in the rear. Right now the left side is a bit lower.

Springs are new and the front suspension height is set correctly and the front end was aligned. I assume it has something to do when you go to the track, making the front end lift more towrds the right side? I just drive on the street and would prefer my car to sit even.

Thanks for any input.
