Man that is real good!
Do ever work on Big Blocks? 
I just bought a set of W9's and with those kind of numbers you could make some serious power. I was going to build a 440 small block, I might have to rethink that and go a bit bigger.
I would really like to get those kind of number out of a set of B1-BS heads. 
B1-BS head doesn't have a tall enough port for that kind of flow. Only so much you can do with a standard port height. Better capability with the Victor head or the Indy EZ due to the raised port.
It would be nice though, standard height intake port and that kind of flow? It'd surprise the crap out of folks.

J,
If you had any tallent we could get 380 out of a set of B1-BS's.
p.s. another very quick street car is going to rumbling around the Carson area this summer. W9 440 in an A-body 
Is that 440 block a 59* lifter bank angle block? I ask b/c I have a set of fully ported W9's for my R1 block but the 59* block with it's 1.875 lifter bore spacing makes me nervous with the push rod angle.. I know I can run the offset rocker but the little 5/16 push rods is less than desirable for my boosted application.

How you think the 9s compare to the 8s that you have worked on? just asking because there is always a talk about which will make more power and w9 cant make big power.
So far I think W9s have not been given fare shake I think they will make good power but most of the W9 stuff was for dirt track ports and chamber all wrong.
I did not like the W9 for same reason but now that I have worked with them they are nice, Intake port has more meat in it than early W8s.
Draw back is the valve are .100" closer to exhaust side of head.(this will hurt small bore more and small bore with big lift .750"plus will be at disadvantage)
I think if you are doing W9 engine you should run 4.150 bore or bigger then valve placement would be a wash.
The other thing I am updating 3 sets of W8s right now and they are all a PITA start with new W9s and dont look back.
I think my W9 in max effort NA deal can do 850~900HP to be seen but the data on the head backs this up now just need some one to step up and build one.
