Very nice. I have an '03 z06 with similar results and a very different way of getting there. I was working around California emissions. I think this is a pretty cool comparison! This graph is on 91 octane. I was able to pick up about 12 ft lb in the low range on e85.
What really surprised me is how down on torque I am compared to you at lower rpm. Damn long tubes and no cats are working well! I feel like the dual 3" is taking away some low end power from me for sure, but the convenience of a nearly bolt-in x-pipe won me over. It's a nice 304 stainless x-pipe from Corsa too and the car sounds amaaaaaaaazing compared to stock.
AFR 205 heads w/ 62cc chambers
SLP 1.85 rockers (600 lift with stock cam)
Smith Bros 7.45 and 7.50 pushrods
Ls7 exhaust manifolds and cats
Corsa 3" x-pipe mated to OEM titanium axle back
K&N intake
Ported throttle body
160 thermostat and a good tune

AI emailed me this morning... should be getting my heads within a week. Anxious to get her back up and running and see where I'll be at. Once I get the tune sorted out (I do my tunes over email) I'll be heading back to the dyno!

I saw you said you wanted around 450 with heads and cam so I thought I'd share my results. I achieved the below with stock heads, intake, throttle body and tstat. I know aftermarket heads set the next level for future upgrades, but I got close with the stock 243's.
447 rwhp / 406 rwtq.
Mods: Tick Performance SNS Torquemax Stage 3 cam, Brian Tooley .660" lift springs and titanium retainers, SLP 25% under drive crank pulley, Airaid cold air intake, Fast 36lb injectors, Kooks 1 7'8" Long tube headers, 3" X pipe no cats connected to the stock titanium mufflers.

New results are in. We'll call it 435hp/400tq. Here are some graphs I made showing before vs after.
New stuff:
AI 226cc cnc ported 243 heads, milled ~0.030", stock valves with PSI 1511 springs.
PatG specced EPS cam: 226/230 .604/.604" 113 +3

2003 Z06, LG headers and catless X pipe, Vararam intake, stock over the axle and street tune. A/F was set at 12.8 for track duty. This is SAE(corrected), uncorrected it made almost 400rwhp.

You planning on doing anything else to the vette?
I would like to hit up the PCA event as well, but work conflicts . I'm a good 4 hours away.

Nothing spectacular, but here it is.
2003 Corvette Z06 with 39k on the clock:
-Kooks 1 7/8" headers
-Kooks catless X-pipe
-Stock Ti exhaust
-Airaid full air intake w/ dry flow filter
-EFILive Autocal w/ remote tuner
389hp/378tq SAE on the best run. Correction factor was 0.98. Dynojet.
Pretty much what I expected, but always nice to have some real data for comparison purposes. Doing heads/cam here soon...hoping for around 450!!!
