Yea no doubt if you have increased VE with the NA setup, it will make more power in boost. Just depends how much he wants to spend since he said it was a "budget" build lol. Thats some damn good mph, but Im sure the turbo setup has a lot to do with that mph just as much as the heads and intake do. I also have arp rod bolts, studs and ls9 gaskets and torqued them like you suggested George
