It's a nice combo.
Bozz, for an LS2, I would expect upper 400s easier than an LS1. It has more CID and more bore. It should be good for 15ft-lbs out of the gate and at least that much HP. And one thing to note: EPS cam. I've never seen a dyno with an EPS cam taking a ****.
I recommend AI to folks. They make good heads. In the right combo, they do well. Have their been some poor examples? Sure. In at least one case, the cam was not right at all for the heads.
Now, do I wish Phil did things a little differently with regards to customer service/communication? Yes. But, I won't hold that against him.

That is badass, I have the same cam in my 5.7 but my heads are some lightly hand ported 799s. Do you know how much yours are milled?
And yes, this cam puts the old 230/224 reverse split cam I had to shame everywhere in the powerband. It feels like it picked up 50ft/lbs down low over the old combo. It drives amazing but then pulls hard as hell from anywhere in the powerband.
One of these days I need to go full port on the heads and get some 1 7/8" headers.
BTW I have 3" duals with dual cutouts about a foot off the collectors and the car consistently picks up right around a tenth at the track and a mph with them open. I wouldn't be surprised if the gain was from it rather than the timing.
Do you know what you're timing ended up at? I kept getting faster up until I hit 27.5*
