With this bunch, probably not. We either figure out how to lower them or the restoration guys want them set to factory stock height.
I'd talk to the spring shop your local 4x4 guys use and see if they can re-arch your springs or build you a new set with more arch for the lift. On the rear you could use a pair of lift blocks just like the 4x4 guys but that won't fly on the front. You might even check with a 4x4 shop and see if springs with the right width and length are available with the lift you want.
This is interesting, it gives the measurements of the springs

You might contact them and see if they can build springs that will give you the wanted lift.

http://www.generalspringkc.com/default.asp I don't know anything about them except what we see but It doesn't hurt to ask and they do do custom work.
They are in Olathe Ks and 186 miles from you according to the map.
