Heads/Cam guestimate
im thinking of doing heads cam on my '02 mn6 c5.
here's the setup i'm thinking of: LS6 heads (ported & Polished), LG LongTubes, FAST Intake/90mm TB, G5X3 cam, Tune and beefed up valvetrain. how much rear horsepower would i expect (i'm aiming for 450rwhp or more?
is this a good setup or not. i need opinons.

The tune will make a significant difference as well. But don't get hung up on peaky #'s if you have a solid, smooth torque curve.
My Cartek 3X H/C set up made ~450 rwh with all similar mods as yours except the ud pulley. This was through mufflers and high flow cats.
If you haven't already done so, be prepared to beef up the rest of the driveline. Tranny, output shaft (atleast primary drive axle), clutch, and consider the rear if you'll be drag racing it.
Your results may vary depending on use, but I calculated my costs of power adding as such:
For every $1000 I spent on making more power, I spent $400 preparing the car to handle the extra power without going "boom"
