Although it might not be accurate in my model, the B-52 wing is set at six deg incidence, and while it does fly a little nose-down in some circumstances, six deg worth would be worrying;) Heh - not that I haven't seen some of my FDMs for it do exactly that:)
Take a look at the NACA wing section lift curves. The ones with a camber have a positive lift coefficient at zero degrees alpha.
The lift is due to the net pressure difference across the wing surfaces. The same action (pressure difference) that causes the lift, also causes the downwash. You can't have one without the other.
