No, no 450 rwhp, you should break 400>410 if compression/quench/tune is right

With that cam you "MIGHT" reach 400 rwhp and the other mods you listed. You are A4, which loose more horsepower to drivetrain.
You will NEVER reach 450 or close to it with the mods you listed.

That was what I was sayin'. 
I'm hoping for close to 430-450 with my 224/228 cam and fairly heavily ported heads. When I upgrade from the LS6 mainfold to a Fast 90, I'm hoping for upwards of 460-470.
That's with a bigger cam and heads that flow 50+ CFM better than a set of LS6 heads.

To get anywhere close to 450 rwhp A4 you would need either the best heads, cam combo with efficient stall. Like AFR, AFR cam, Cometics etc.... Basically, mucho $$$
Or you need a Big *** cam, flycut, decent heads etc..
Other option is Supercharger
450 is not easy on A4, I've never seen stock cubed 500 A4 (there could be one, but I've never seen it)

I know I'm getting in here late, but here's my dyno info with LS6 heads and GM Hotcam, with supporting mods:
