Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best

@273 the more efficient(better designed) a port is, the higher a velocity it can operate at. High velocity is "free" supercharging, augmented by complimentery runners. They actually work better with smaller valves because more curtain area is used, which allows for less shrouding as well. Poorer ports tend to work better with larger valves deshrouded because they need as much low-mid lift flow as possible to crutch poorer high velocity flows, most OE ports are poor to decent. Very few are great, but some can be modded to be very good/great, so that's where it stands.

That's a good generalization.
There's also some practical considerations.

Higher velocity means higher momentum and smaller turning angles. A smooth port that's as close to straight as possible can function well at higher velocities than a port with sharp changes in direction.
There are upper limits to port velocity even when perfectly straight, and it can get complex. Especially as it flows across the valve and into the chamber and expands.

Basically: it depends.

The carb, heads, and intake all need to match the intended flow capability of the shortblock.
