Ride height with SS springs

Quick question...when you install SS springs on a Duster, how much does it raise the body up compared to stock? If you want to run a significantly wider tire, do you still have to minitub it?

Thanks.
I put in two passenger side 3200lbs SS Springs and used a 1 inch lowering block on my '68 A-Body. I run a 275/60-15 Nitto Drag Radials on it with 8 inch steelies.
