facerape;
I don't think you can eliminate the rear lift blocks for two reasons. One reason is the bumpstop is part of the block and from what I've read, the spring pad is not flat, but a little high in the middle which would cause your rear axle housing to rock back and forth. I read this on some other web site.
But I'm pretty sure it's true.
You could check it out while you have it all apart, and let us know what you find. OK? just my 2 cents
