Your peak numbers are low because your hp is peaking in the 5300-5900 range rather than 6200-6600 that would be more typical for a cam of those durations. Similarly, your torque production drops off a cliff after 5252 ... all of which indicates that your manifolds are choking off flow.

This may sound stupid but couldn't you run some shorty/mid length headers to a catted y-pipe and still be smog legal? I know the gains wouldn't be as much as a nice longtube setup, but I would have to believe you'd gain some power going that route. You've gotta let those heads/cam breathe.
Just my $.02

That combo is so similar to mine..I'm glad it runs well for ya. I know shorties
are FAR less ideal than LTs but you may eventually want to try some BBKs
w/2 and 9/16" NAPA donuts. They look nice, fit well, and kill 25lbs. off the
nose of the car. $400 and a retune would give you that 380 that you had
originally wanted...plus enhanced MPGs

There is nothing wrong with his numbers. The stock manifolds and cats are that bad! Headers are worth alot on stock motors...even more on modded motors. With his combo he could easily see 25-35 rwhp from longtubes and no cats. The exhaust after his stock cats and manifolds doesnt matter as much due to the choking being right off the heads!

Your numbers are actually higher then I'd expect with stock exhaust manifolds. I have a bigger EPS cam with the same heads you're running and put down only 347 to the wheels with stock exhaust manifolds.

I had a c5 Vette with stock lq9, ls6 intake, stock c5 manifolds and a 236/242 .580/.590 116 regrind cam and it made 389/378rw with stopped up injectors. Cleaned em and it felt like a small shot of nitrous. Do my numbers sound right?
I never got it back to a dyno do to being t-boned shortly after
