30rwhp is a good gain honestly. Seems right to me for LS6 intake and ported stock TB. Seems like an honest dyno, not an internet hyped up dyno queen.
What tires, gear, wheels, MAF, trans, flywheel?

Auto, M6? Stall unlocked on dyno, clutch slipping?
What kind of dyno? What was the WOT AFR and timing?
**** dyno numbers, they can be all over the place. Take it to the track and see what it traps, assuming its tuned properly.

AI states 20-30 wheel gain from the port. And going from the 853 head to the 243 I was just expecting to make more I guess. I understand the dyno is just a tool...

you should be over 400rwhp or close to with the MS3 on stock heads alone
This might be a dumb question, but you retuned with the new heads?
Are both dyno numbers from the same place? If not, forget about it; if so, as the other folks have said, dyno numbers are a pretty arbitrary thing. You aren't going to tape your dyno sheet to the windshield; does it FEEL fast? If so, why sweat the dyno sheet?

I think those are realsitic numbers, not low. This is my graph of my old 346 setup that is very similar to yours.
I had a 346 stock bottom end ls6 intake, full boltons, stock rear 3.90 gear locked 4l60e converter(4000), TSP ported LS6 heads, 235/243 cam
My car is full weight and I weighed(Well back then lol about 210 lbs) and it would trap 113 - 115mph all day long.

My old friend pulled 430rwhp with H/C as well full bolt ons. Its about 15more then you but as stated above doesnt matter take it to the track and see what it runs. Some will say they pull 450-460rwhp with your set up and some will be lower, maybe on another day you will pull higher. If you can do 120+mph in the quarter, your car runs strong. With a Fast Intake Manifold and bigger throttle body you will gain more and be a little happier with your numbers but dont get caught up too much.
