You'll want to get a custom cam to match everything properly.. I would recommend you going solid roller if you want to turn the motor that high all the time constantly.
On the heads I would call Chris Frank for one of his programs on the LS3. The big runners love the tach north of 7000 rpm!!

who is he with or you have a number for him??
4500 with 1050 dom will be wayyy to big for 600-650 hp (more like 430+ci and 750+hp)
dome a few of the cfm programs they all show for a 408 turning 7000/8000 rpm to need a 973.9 cfm to a 1130.8 cfm. so i was going in the middle.

Chris frank is frankenstein heads.
408 @ 8000rpm is more like 700-800hp. Then maybe carb etc is big enough.
But if you want 600-650, could get that from stock ls3 heads and 230s/240s cam on <108lsa

As for the Cam, I am a fan of the Cam Motion solid rollers. They also sell both the Jesel and T&D rockers arm assemblies.

Frankenstein Racing and Cam Motion LLSR all the way. Chris Frank knows his heads, and Kip at Cam Motion knows his cams. Kip has by far been the best guy I've ever had the pleasure of dealing with. Customer service at Cam Motion is great.
My stage 1 FRH ported ls3 heads flowed 390/255. I don't remember what the stage 2 flows.
