You won't get a thing out of it. Don't waste your time. There are a few that claim you will but you'll never notice it. Been there. Tried that. Get a standalone ecu first. The airflow meter is the biggest intake restriction so freeing up anything else before it isn't going to help you.

The 6-port 13B's have good intake breathing stock.
The only area for improvement is earlier intake opening.
For that you have to bridge port the side irons, or bevel the rotors.

Not worth it unless the intake is already removed and you are very bored. If that's the case, then just port the flanges to match the gasket and call it a day. Virtually no gain.
