I use a 1" Solid block on my stock rear springs. I had 2" hallow blocks and I got bad spring/axle wrap from them. After about a year in use. When I changed them out to the smaller ones. I notice a crack in one of the 2" block. Good thing I changed them out. As for the 1" solid block ..spring/axle wrap isn't to bad now.
Just giving you a heads up what to incounter with blocks. IMHO, I would use a 1" solid block for the rear only. IF you need some lift. Others may tell you differently.
