Street Edge Drop Springs?

I currently have the back of my truck dropped on 2" drop blocks, but want to even it out to the reindexed torsion bars up front. I still plan to use the truck as a parts hauler from the junkyard, so I can't go monoleaf. I'm not interested in doing bags, and 3-4" drop blocks concern me about axle wrap and clearance from the u-bolts. I've read up about de-arching the leaf springs but I'm worried about load capacity if I do, and don't know where I could even get that done locally. I've been exploring the option of possibly doing 3" drop springs with a 1" block if the springs aren't low enough. I know Belltech makes some for $150/side, but I found these Street Edge drop springs for $210 a pair. Does anyone have any experience with these springs or recommend drop springs in general?
