highest NA dyno with a FAST intake?
I think LG is the closest they made 680rwhp with 500ci very mild ported heads and with stock ported LS7 intake from what I remember..
Did you buy another set of heads?
I really think with very good ported/milled heads (12:1 comp) + ported Fast 102 Intake + 102 tb and maybe EWP you can get the magic 700rwhp from your car since your only 50rwhp short.

Good luck.
