I would use a stethoscope to try to isolate the location of the noise.
I had a noisy lifter on my old motor, but careful (tight?) valve adjustment calmed it down. I suspect it was due to a worn valve guide.
FWIW, I think you are correct that loose elephant feet can cause some noise, but I have not found that to be a huge concern.
What cam are you running? What oil? Is the noise there all the time or when warmed up?
FWIW, I found that adjusting the valves when the motor is still somewhat warm makes it easier the feel the correct adjustment. When the oil, like 20-50 is cold and thick it is a challenge to use the feeler gauge accurately, IMO.
