odd loud clunk when warm

Hope this hasn't been asked before. If it has please direct me to that post, thanks.

When cold the 540 sounds fantastic. once warm there is an odd noise emanating from what sounds to be the valve train in form of a cyclical clunk. It increases with engine speed. I've used a screwdriver and stethoscope to "listen" but cannot find any abnormalities in the cam area. Any suggestion is appreciated.
