Hotchkis to qa1 coil over conversion--which springs

[tumper93]

I recently installed the hotchkis front coil springs on my 68 Camaro and found a great deal on some tubular upper and lower control arms. Since I will be replacing the control arms and need some quality shocks I have decided to sell the hotchkis springs and switch to the qa1 coil overs so I can adjust ride height and get a good shock all at one time. My question is should I run the small block springs or step up to the big block springs due to their higher spring rates. The car is a small block,aluminum head,intake and w/p with power steering. Anybody have any suggestions on which to use or ones they a have used.
