You're going to have a lot of blowby if you don't have the cylinders honed again when you put those new pistons & rings in. The rings won't seat properly. I have stock bore SRPs and they slap when cold as well. It has nothing to do w/ what size the bore is, it has to do w/ the silicon content of the particular piston you're working with. Arias, in particular, has been known for more durable pistons, although the downside to this is that they slap a lot.

 

as long as you did a good hone job you'll be fine, its the h22/23 blocks that need to have new sleeves installed.
