Ported my Super Victor today

Correct. No one should buy a Victor 340 and expect to bolt it up to a 340/360 head without porting, as the ports are 318 size OOTB. But that too has it's advantages.

Mind saying what benefit you found with the runner smaller than the port?

In all my testing, if we left the port small we lost power. If the intake was the same size, or even slightly bigger, we made more power.
