None, no advantage. MAYBE, if your a nutjob, you could prob weigh 5-8 lbs of weight loss. but seriously, thats not gonna make it into a 12 sec car, or track monster.
For anyone in the future who buys your car, or your cylinder head, the air injection ports will be plugged solid with soot.
Thats the only negative i can see from it.
Either way, i say leave it. doesnt hurt anything.

Not if your state doesn't test emissions.
