Or are they just covering themselves legally, by stating drag use only?
Not a case of liability- the springs are tall and wound w/a smaller wire to get the front end up relatively easy yet allow it to settle back down for better aero.
In a street app, they'd pogo pretty bad and depending on the shocks, could bottom out fairly easily.
I've used 6-cylinder springs in both F- and G-bodies w/no problem. Car sat a little lower, but no issues w/alignment or bottoming, etc.
V8 springs should be plenty for a BBC w/alum. heads.
Otherwise, there are springs spec'ed for the BBC from the beginning, like Landrum
