I actually purchased that package, but never installed it and have since traded it for an STS kit. Although I never ran it, I think it's gonna run a little short of your goal. I'm thinking low 400's to 420ish. Anyone else care to chime in?

I'd say a little 50 shot will get you there plus some Actually I agree you will probably be a little short of your goal. With a 90/90 or 92/92 setup I would expect around 430-435. The limiting factor is mainly your cam. A good set of ported LS6 heads can support 450RWHP you just need a cam that's a little bit bigger and matched for those heads. I would contact Patrick G on here and he can spec a custom cam for you to meet your goals. FWIW on my last cam-only setup I made 427RWHP on stock LS1 heads with all bolt-ons minus an EWP and through a pacesetter Y-pipe.

You want 450 rwhp.
If you have a M6 and a 10 bolt or even a 12 bolt.
This is straight from Ron @ Vengance
VRx4 cam (228/230 under .600" lift) @ 112 LSA
Ported 90/90
TFS As Cast Heads 215
Yella Terra Rockers
With appropriate springs, pushrods, oil pump, timing chain, tune, and supporting mods which include fuel pump and #38 injectors
Will do 450-460 all day long.
There are plenty of dyno sheets to support that statement.

that cam looks like it has some decent lobes.
depending on how good the heads flow, if you milled them for more compression, ran a ported FAST, electric water pump...and had a dialed in tune.
i think you could creep up on 450rwhp....i would think 440 would be more accurate.
really boils down to the heads.

His cam isin't correct but that doesn't mean it's too small. I've had cams under 220° @ .050" do that on the right heads.
In the end unless that dyno is happy you will not make anywhere near 450rwhp with those parts out of the box.
