Rear end lift...Need some input

I went with General Springs "383" weight rear leafs even though I'm running a 340. They are 6 leaf, a bit stiffer than the springs for 340,318 etc., and stock ride height. $299 a set. My front suspension is all tubular with a drop spindle so to get the car setting better in the rear and tone down the "stink bug" stance, I had the leaves de-arched 2"
