317s or L92 heads?

I have a 99' LQ4 I planning a blow thru turbo build on it. Looking for around 600hp with stock rotating assembly, which head do you guys recommend stock 317s or a set of L92?

Personally, I'd go with the 317's, but I really don't think there would be much of a difference since there is boost involved.

317s with stock bore size...l92s will fit a 6.0 but are not optimal as far as valve shrouding is concerned...cathedral ports make killer power
