How to get the front end down?

[Strange]

I have the rear end figured out but not the front. I want it to lay frame but cannot afford a drop member. So Z'ing the front is pretty much my only option. How much can I raise it up? I read on a thread that you should not go more than three inches, is three enough lay frame while clearing cross member? Should I use drop spindles in conjunction with the Z? Any help is appreciated
