I'm currently having a 496 stroker being put together by Nick Wilson at Compuflow and it should be on the dyno within the next 2 weeks so I will have some better info then but as far as flow numbers I have aluminum Indy SR's that Nick ported and he told me they are flowing 329 CFM on the intakes and with the 6 pack manifold attached the flow varied from 276 CFM (#1) to 285 CFM (#5 I think). Even though the 6 pack manifold has a stage II porting done by Hughes I was surprised at the big drop in flow.
