Is it still making the noise with the valve cover off and running?

Is it the same ticking at the fuel pump? The fuel pump will make a certain amount of noise with a stethoscope held to it. BUT I spent a fair amount of time chasing a mystery tick on my 241 hemi. I finally pulled the fuel pump off and found the arm was broken in a spot and it turned out to be my ticking noise. I Replaced it and the noise is gone.

Could be one more spot to investigate!
