FABO racers, could use your help to win a bet.

I would venture to say the NOS will get you a clean run even with that gear and higher RPM range as long as your valve train don't start to float. If the valves float you if course could have damage as you know. I would check your valve springs just to be sure. The rest of the engine should be able to take it no problem. I would also probably take out your revv limiter. Most guys that Run NOS don't use them. An NOS backfire up in RPM when it comes off the limiter is not good either.
