One loud ticking after valve adjustment.

I’m running a ‘63 Dart wagon with stock 225 three on the tree. When cold there is no unusual noise. Using a Stethoscope the valve train sounds just fine. All even and normal sounding. After warming up the ticking begins, intermittent at first and when fully warmed it is constant ticking. Stethoscope of the valve cover the tick is everywhere—no loud spot. I listened to the fuel pump and the sound is there also bit not really a lot, if any, louder than what the valves sound. The tick is everywhere I listen.

My suspicions are two. Possible fouled up top of valve stems so the rocker arms don’t contact straight. I had the rocker arms resurfaced at the machine shop. Didn’t notice any valve stem problems, but I wasn’t actually suspicious of them. Still, could be a problem but the rocker arms weren’t too bad. The second suspicion is the fuel pump. Don’t know what would cause fuel pump noise unless the eccentric is badly worn or the arm is noisy.

Previous owner did overhaul the engine about 40,000 miles back. From our two or three conversations he seemed to be an informed technician. I’ve found nothing else that would make me doubt his skills.

Anybody have any ideas. This is kinda embarrassing when at stop lights listening to that tick.
