Have you been able to figure anything more out? I have a very similar sounding issue. New OEM block, head rebuild, all gaskets the works.
Only thing I can think of is that the gears under the timing cover were nicked, even tho I didn’t visually see anything. Same boat as you having poured...
So you did a complete rebuild and then had this noise, leading you to reopen and replace the crank & oil pump drive gears correct? I’m just wanting to clarify because I am in that boat. New OEM block and full rebuild, and have this exact same noise on startup. Noise is there with PS pump...

Ticking from power steering pump after startup. No tick with pump removed. Losing my mind as this somehow is seemingly the only issue I’ve run into with an entire engine...
