Stock L92 injectors? They are only like 33lb. I'd say you need more fuel. Idk though. I'm not a expert. Although it's depressing me, I'm afraid when I get mine done, I will make under 400.
I've seen some guys make 370wheel with full bolt ons.

Headers are small for that head/motor combo
On a 6.0 I did...we went from a ls6 intake and tb, 13/4 headers with 2.75 y pipe into single 3"
To fast 102/102, 1 7/8 headers with dual 3" into single 4"
Dual 4" air intake and gained 60/60 thru a 4000 stalled auto
410/350 to 470/410

Like said above, don't be too concerned over numbers.
Do you know the timing? AFR? Is the converter locked? How high were they turning it? With that cam and heads you should really have to turn it to peak out the power.

380rw through a stalled 4L80e w/ 4.10s.....that's not bad for a cam only 6.0L with L92 heads.
Manual LS3 Cars make 460ish rwhp with that same cam and they have much more compression that you do, and much less drive-train loss. I think your numbers are where they should be considering what you have.
If the numbers mean that much to you, get it on another dyno. If it feels strong and runs the numbers at the track, I wouldn't be concerned.
