What are your plans for it? N/A, nitrous, FI? What grade of fuel are you planning on using?

I guess i missed that. Just use a compression calculator, plug in your info and see what each piston will give for CR. I'd stay around 11-11.5:1 at most to be safe on 93 octane. Make sure the pistons are made for nitrous as well.
