All pulley combo at that point. You're obviously not looking to run 18/20lbs of boost SBE. 12lbs should be more than safe, especially if you run E or meth.

No plan for E or meth, I have research quite a bit and safe PSI is all over the place. Ultimately I'll most likely end up going with pulley combo my tuner is comfortable with, I think I'd like to be in the 8 to 10 PSI range. I really am not sure what a realistic HP goal is with a mid range cam and SC with supporting mods.

stock pulley setup is 8lb of boost. 8" lower and 3" upper. i think a safe boost range for a ls3 is 10lbs

And I also just learned that dedicated motorsports has an exchange program which I would not have known with out asking the question. I'll look into this if I decide to go the ported route.

Great reply Joe! That's why we have this forum, to ASK, and LEARN from the best of the best! Those who have been there, done that. Saves a lot of time, plus I know you have already done your homework, and research, I know you! lol. Keep it going sir!
