I don't know if this will help, but you may want to check other sites for the flow of the vortec 350. The heads are basically the same minus 2cyl. Info on the 350 is more readily available.

I spend a lot of time on the web, a while back a guy was selling these heads on ebay and he enclosed a comparison of two different heads he had flow tested. I'm in the process of trying to decide on what heads to use myself. If they made an aluminum manifold I would go with the new heads but the Marine Manifold for those heads is cast iron and about $400 so I'm going to hold out.
