I have a question also. I just got a FMF power bomb header and the damn thing is tight against my motor where the bomb part of the header is. Will it hurt anything or should I just send it back?
If it's touching send it back, should be a small tolerance. If not it will vibrate a hole in the header and jug or crack either. It would also cause more motor temp with it tight/touching. IMO I'd send it back.
