They still"season" blocks, but it's not the same as they used to( let 'em set outside ,etc.) But they do cryogenic treatments that are supposed to do the same thing...or achieve the same results. I don't think I've heard of that with aluminum blocks either. You have to have a singular metal to do it, an aluminum block with sleeves wouldn't fit in that category. I would think that any treatment on an aluminum block would have limited success since the cylinder would create some changes from the installation and boring.
