Show That Lowered A-body!

Oh well here I am again asking questions. I've read where some people are cutting down the LCA bump stops to go that much more lower. But how much up travel is needed to be safe ? I'm 1/2 inch off the stop.

My front end was sitting on the bump stops when I was driving it around. I noticed no ill issues at all. I had hotchkis rear suspension and Doctor Diff front hangers, which lowered the rear almost 3 1/2". I turned the front down to match.
