I had a 1969 Z-28. Back then the fad was to have the front higher than the back (remember). Gasser style. Most guys were using the screw in type spring adjusters. They would definitely ride hard.

So I decided to buy a set of heavy duty station wagon springs and have them installed. Car rode like a truck. The height changed all the geometry on the front end and the garage was barely able to get it aligned correctly. Something to think about.
