What HP/TQ are stock LS3 heads good for?

[blake-b]

I understand a set of ported/polished heads make more power or make it easier to achieve power but at what level do the stock heads become the "bottleneck."

I ask because in Feb, I am definitely doing a cam and kit and maybe heads. I am looking ultimately for 600-700rwhp (down the road) with the use of either TT or a supercharger. I just can't make the decision if p and p heads are going to worth it costwise or if they are even necessary. The use of FI on a stock bottom end adds stress but if p and p heads make the power level easier to obtain, it should make it easier on the bottom end?

Help?

It is Pretty hard to find that bottle neck with Boost, Probably above 900 HP.

Stock LS3 heads are Pretty amazing, We make 880 Crank HP with a cam and 12 PSI boost.
