If this is a freshly rebuilt engine, I haven't read anywhere that a search for the noise was done. Usually takes a few tries to find the noise, and it can move as it did in my Cobra Jet (there we found a bad oil pump gasket was causing air to be pumped to each lifter).

But yank off the valve covers an use the stick method of locating the noise source. Lifter will stay quiet after ten minutes of warm up even using old junky oil. Install the clips for the arms to stop oil spatter.

On a freshly rebuilt engine, it was famous for the rocker arm studs to begin moving outwards after hot tanking. Considering how much valve spring pressure these enignes used to have, they ought to be moving right now. You can tighten up the nut now, and the noise comes back a week later on after things have moved.

Chilton used to be rather on top of everything. If he has a once California engine, it then gets timed at TDC per Chiltons. Ford said six degrees, but the book was written months before the engine was cast up. Timing via ear then works out best often.
