I can comprehend fine thanks. There is a place for smaller ports depending upon the build. You cherry picked one data point to try to make your point, but chose poorly.

For the record I am using some tiny port 413 RV heads on a 440 RV engine I am building. Been told by many that they are junk and wont make any power. Fact is they are the best heads for my application as the engine will never see north of 4500 rpm. It is all about low speed torque and keeping part throttle velocity high trying to get more efficiency.

I could present many more examples of the same "inconvenient facts" which you would then ignore because it challenges your "chosen narrative"

The Dart went 8.5s in the 1/8th. Mid summer he picked up a single plane M1. That change dropped it to 8.10 in the 1/8th. No other changes.

So going from the most restrictive single plane with no plenum to what some would call the best single plane mopar produced and it picked up....no way. :poke:

An engine uses what it can not necessarily what you give it.
