Any suggestions of what this sound might be? How does one start the process of checking for valve problems?

My Jensen Healey's engine recently began making what sounds like a valve tap. The noise ranges in tone and volume from that of a metal pen being quietly tapped on a metal desk to a loud almost popping sound. The noise will usually quiet down at higher revs, but not always. The engine seems to run rougher when the noise is louder (but that could just be my imagination). The head has been reworked at some point, as evidenced by the bent valves in a bag O'parts provided by the previous owner. Any suggestions of what this sound might be? How does one start the process of checking for valve problems?
