Port Match Intake Manifold - What abour AFR?

[RedPhoenix]

I have all week off so i wanted to do a little project. If i port match my intake manifold, how skewed will my AFR be? I dont have the ability to change my AFR, so will port matching make a big problem?

It will be fine. If there is any increase in air flow the AFM will notice it and adjust the fuel to suit.

If you were doing it on a MAP sensored car it would be a different story.
