Default Sti block to NA

I recently bought a 98 impreza rs with a blown shortblock. I have access to a rebuildable sti block. Does anybody have any info on using the sti block and converting to NA. I would be reusing the 2.5 NA heads. From what I read in the service manual, the bore and stroke is the same. Could I just swap new NA pistons. I am looking at JE pistons. Would there be any benefits from using this block, with Sti rods, Stock Sti Crank, and the JE pistons. I am pretty sure it could handle more abuse. I know I have to check and make sure the rod length is the same. I saw they have two different rod lenghts for the Sti shortblock.
