One loud ticking after valve adjustment.

I have had the stock mopar fuel pumps tick before, sends tick through the whole engine by means of the eccentric on the camshaft and then through the camshaft itself up through the engine.

If you take you take your fuel pump off and wiggle the arm up and down and hear it clicking that is probably it. Fuel pump arm in the pump should be snug and not able to rattle around when it is working property.
