one inch drop coils

[65truckowner]

I have a set of 1 inch drop coils in the front of my 65 c10. I now have the engine installed and most of the front clip and the springs hardly moved at all If I stand on the frame and bounce it they seem really stiff. Will they settle at all once I start driving it? I was planning on installing 3 inch drop in the rear but am afraid the rear will be lower than the front
