The mismatch was not the problem with putting a 460 Victor on a PSE, it was the airflow. Why put a 550cfm manifold on a 320cfm head? Worse than the Dove spyder at anything below 6000rpm. It all comes back to having the manifold flow around 120-125% more than the head for a race engine that uses a cast intake. JMO, but plenum design, runner taper, and angle of entry into head are more important than maximum airflow. I would much rather have a smaller port continue to flow air faster at higher lifts and water pressure than one that flows a lot of air, but shears over the short turn and loses flow at any lift. If a port continues to increase airflow above 28" on my flow bench, I will sometimes check it all the way to 48" just to see if it will back-up or go turbulent. If it does, the shape is wrong somewhere. Takes a lot of patience to figure out what causes a port to go stagnant or back-up flow, and years of experience. What looks good does not necessarily work on the engine, or on the flow bench. JMO, but the more I learn, the less I make adamant statements. There are always exceptions to what is accepted as "gospel" from the past. Joe-JDC.
