valvetrain noise 5.9 magnum

I was talking to an older mechanic friend of mine who has been working as a mechanic since 1990 and he knows his stuff pretty well, he has some expierence with mopar's but he is very knowledgable when it comes to fords. Anyways i was describing this noise to him that my 360 magnum is making and i asked him if he sounded like a lifter going out to him and he said if it was a lifter it would be more of a ticking noise and the sound would get louder with more throttle not go away.
Is he right?
