Tapered intakes, port velocities etc

[Nass Jeff]

SAE 871977 on a 3 valve Mazda V-6 is good for intake design.

Does anyone know of any good SAE articles on manifold/port/valve design?
I remember reading a good one by GM on their Vortec engines where they
gave some good real-world data (ie. dyno graphs) of various port
configurations (mainly size). I believe there was some info on the
manifold design they chose and why (it had the widest torque curve if I
remember correctly).
