If style with a hose on it remove the end piece. Any exhaust leak will be quite noticeable as air passes by the end of the open hose.I have a stethoscope and frankly I’m having a heard time isolating the noise. It sounds loudest when touching the head between the headers and valve cover, but I could also be wrong. No flat tappets.
