This is all part of putting a really adjustable suspension in a car. You need to adjust it. The motion ratio of the coil over is such that 1/2" of coil over travel equals about 1" of wheel travel. On a lowered car we don`t have much jounce travel left so the coil over shows even less. That looks funny to people at first but as long as the coils aren`t actually touching at any point (coil bind) you`re fine. Using a longer spring would mean that it`s compressed height is also higher and it would coil bind before the shock has used it`s full travel. It`s permissible to use a 1" coil spring preload spacer and it`s sometimes a handy tuning aid but it shouldn`t be necessary with 575lb/in springs on a small block G body. We can`t help without enough information though. We need more info as far as where the lower seat is (can`t see it in the pic). Posting threads like this before the client has even spoken to the vendor is almost always counter productive because you end up with a lot of wild speculation from (well meaning) people who have never worked with the system before. It just muddys the water and makes it harder to get things done. It`s best done after the tuning is done,then it can be a help to others. Mark SC&C
