First thing is compare the rate of the springs. You will probably find that even though the stock BBC springs are talller, they are lower rate that the Hotchkis. Still compare them. You may need a stiffer taller spring. I would compare rates and then decide. Was conditions do you have that dictate the ride height being low? Is your exhaust dragging or is the whole car bottoming out or what. I think we are going to need more information. I would assume that your springs were drop springs, then you added drop spindles? I would assume you have headers on your car? These things all add up. Let us know.
