Can't help you out in location but from what Iv been reading. It is better not to port the mani to the throttle body. Works best with a step think is what I read. (Correct me if im wrong guys)

nothing wrong with porting the factory, but like he said, from what ive read a 4mm step is great. I have a 2mm step on mine. 60mm b16 tb, and skunk 2 pro series manifold which is 62mm

It's an anti-reversion step that captures pressure waves traveling backward due to intake valve closing events and/or rising pistons (before intake valve closing events).


Also, for us to help you, please answer:
First things first: what is (or will be) your setup?
