P.S. while cruising by the Goodrich facility at Paine Field the other
day I spotted a reverse NACA duct tucked under the horizontal stabilizer
of a B 737. It was canted about ten degrees opposite the fuselage AOA
for cruising flight well on to the tail cone.  Didn't have a camera with
me at the time, but I'll keep looking and send a shot when I can get
one.

Maybe that goes along with that upside down airfoil they use on the
horizontal stabilizer on the 737 :-).
Tail definitely lifting down on that bird.

As it should be.

All conventional aircraft have a download on the tail.   This is one of
the advantages of the canard config.  The tail and the wing lift.
