Default LS3 build for boost

Just asking for suggestions/recommendations as its time to build the replacement for the blown ls1. I am going to be using a LS3 block for new build using a 24x crank (due to 02 fbody pcm). Car is procharged and will remain procharged. Was at 10# but want to build for more. Fuel system is currently good to 800-900rwhp

Budget is 10-12k for long block

What pistons would you use? Diamond, Wiseco, TSP, CP?
I am going to probably run around a -20cc dish?

Whats the main difference in rods? I see no need for I beams and I have ran Callies before but that was back in early 2000

Crank. I am reading that stock crank is easily capable of 1k however I am thinking after redoing it all and shooting for only doing once hopefully might as well get a new forged crank. Stick with STOCK stroke due to boost or send it and build it 4.00" stroke?

Heads I am torn between some AFR 230cc 1630 heads or Texas Speed PRC 237cc. Yes I am aware LS3 square ports are better however I want to reuse my cathederal intake/tb/fuel rail/injector setup


thanks in advance
