Ok so I happened to drop by Year One's headquarters while I was attending the Petit LeMans race at Road Atlanta in Oct and ended up buying a set of Patriot Performance Stage III Ls6 heads for a steal. I know they are not the most desirable head out there but it was a great deal (so please, no "You should have gone with ___ heads comments).

I am planning on leaving the bottom end alone other than doing an oil pump. I am just trying to find the best cam to get me as close to 450-500 rwhp as I can while still keeping daily driveability in mind. I do want something with a pretty good lope to it. Already have long tubes, am keeping the LS6 intake, and will be building my own CAI. Thanks for any help!

They are the wrong heads for your motor size. I cannot see anywhere near the numbers you want with those on.
Stage 3 have what 2.08 intake valves?

Not gonna happen and that ls6 will hold you back

So you are saying these heads are for a bigger cube motor?

Stage 3 usually means bigger valves. So yes usually used on bigger bores than 346ci.
So what are the valve sizes in your heads?

I honestly don't know. I've looked for specs but have come up empty handed every time.
