Need some help.

[Strange]

I have three inch drop spindles and three inch bag cups on the lower control arms and a three inch frame Z. My air bags measure eight inches with no air and no load, Will the aigbags inflate enough to get a good ride height? I have no idea how much the bags expand and I cant check. I have another set of lower control arms with no cups, would it be better to use a block off plate on them versus my other ones with the cups?
