Default 408 pistons?

I've been trying to figure out which pistons to run in my 408 that I've been building, and get a little confused when reading the piston specs.. I know my block has been bored .030 over (6.0 LQ4) now with the cyclinder bore now being at 4.030 I'd need a Piston that is roughly in the 4.005-4.010 range correct?(assuming the rings make up the rest of the gap) I just didn't want to go off and order the wrong piston set is all.. I'm not putting it together, just getting the rotating assembly ordered so I have everything on hand when it goes to the machine shop for cleaning and assembly.. but here's what I have so far:

04 LQ4 6.0 Block, bored .030
K1 4.000 stroker Crank
K1 6.125 Rods with ARP 2000 bolts.

BTW it will be a boosted motor when complete, via either a turbo setup or Procharger so Compression needs to be fairly low.

you are thinking to hard. just tell which ever manufacturer you are going to order from what you are building. They will be able to get you the right pistons.
