Could be that simple...remember I had a tick on my 318 at idle, so I doubled-up the header gaskets and she quieted right up. I also used the permatex gold header gasket spray.I have a tick in the motor 360 la .... I can rev it up and ticks with the RPM. I was told could be a header gasket any thoughts ? good oil pressure , temp is good and no loss of power . Thanks
Thanks Ill try thatHook up a vacuum gauge and verify a nice steady needle. If nice and steady, the exhaust gasket leak is the best and cheapest place to go.
