flow numbers
flow numbers I have my flow numbers for my new 6.0 stage 3 heads from ARE
.200 137 117
.300 205 160
.350 227 181
.400 255 198
.450 281 207
.500 294 215
.550 311 221
.600 325 228
These heads are going on my 422, with a 254/254 .610/.610 (I think) @ 110 LSA.
How do these compare to other big bore/stroke guys, and what kind of hp did you make?

Is that an iron block?

nice numbers 
My LS6 ARE heads flowed 327 @.600 lift with a 2.055/1.57 valve and a 236cc intake port. Exhaust flow was very similar to yours as well.
On a 385 stroker 236/242 110LSA cam with full exhaust I made 466RWHP/43X RWTQ. That was with heavy iron disc clutch, heavy DS and billet flywheel.
(Stock MAF, Stock ported throttle body, stock LS6 intake etc)
You should be right around 500RWHP with your added cubes and bigger cam.
Just went 11.10@125mph through cats with a six speed at 3620 pounds last weekend.
Your combo should be a very strong runner!

I hope so! I want to run well into 10's on the motor. Should be able to. My t/a ran 10.9 @ 129 but had 10.6 in it with 533 rwhp. My zo6 has better gearing, aerodynamics, and is lighter. Dont see any reason it shouldn't.
