Block it off...it'll be the same as an exhaust leak. You can get these threaded inserts that screw in the hole, but more than likely, the hole will be all carboned up, and won't let you thread it in.
A cheap but crude method would be to leave the tube connected at the back of the head, then cut the tube close to the back somewhere, and crimp the end with vise-grips and bend it over a bit.
I said it was crude.
It's used to inject clean air from the pump into a hole that's in each exhaust port to dilute the exhaust gasses for lower emissions.
Don't tell the EPA I told you.
