Just got my AS heads. Flow #'s inside.. (now pics) Well, I got my 5.3 stg 2 heads, but my intake, tb, gaskets and bolts did not come 
. But the heads look great. Here is what the flow sheet says.
Jay does some damn nice work!
Lift intake exhaust
200 145 114
300 204 160
400 254 198
450 274 207
500 290 218
550 302 224
575 308 226
This is at 28" of h20
3.9 bore
I believe flowed with my intake
I like the 302 cfm at 550 since my TR224 lift is 564.
Will get pics uploaded later.

Congrats on finally getting them. 
When are you expecting to get your other stuff? As long as UPS doesn't screw up something mine are due here tomorrow. 
Did you get stage 2 or 2.5 heads? Also what size intake valve did you get, Jay said he put a 2.05 in mine.

CS is very good and the heads seem to work ok as well. J/K
His heads are top notch. AFR will be great in time, but it will be a few months.
Head porters need time to get their hands on them and fine tune the heads. Then we shall see some nasty fast LSx motors. Probally by the time they get the AFR heads figured out the 3 valve LS2/LS7 heads will be here.

Yeah my heads flowed close to that with the old valves. 
Oh and I doubt that was with the intake. Still excellent numbers.

He sets up your heads to work the best with your cam and other mods. Since I am only running .564 lift. He ported them to flow good down low as well as up to the .575 lift. He left me the chance to upgrade to a TR230 cam if I wanted. But don't have any plans to do so.
