It's a hit topic because it is very real and although it doesnt hurt anything its not the most enjoyable thing to listen to so if my motor had it (which it does) I would try to eliminate it by doing a over bore if it doesnt which not all do then I wouldnt worry about it. I'm not sure if your gto does it (iirc gm helped the problem in the gen iv motors) but if it did you wouldnt like it lol
