Hydraulic Lifter Tick

Hey all. 1950 2302 with a 327 and Ultramatic, 7 qts. fresh 10w-30 last week, new filter, Carter 643SA, 6v, points, mechanical pump... unmodified. Trying to get opinions on what (if anything) can be done to address a ticking lifter while the engine is assembled. The tick has been there since I bought the car (last year), and only becomes noticeable when the engine reaches operating temperature. The idle does seem to be effected by this tick, though it's otherwise smooth. Under load - accelerating and cruising - it's outstanding.

Here's a video of the rear eight valves - I believe the culprit is valve number three from the front (which also appears to have a shadetree shim between the lifter and plunger).https://drive.google.com/file/d/1o8heOiQPoFbxdV1ipD13-cz2pwFfKwRW/view?usp=drive_link

This is the vehicle driving earlier in the day before I took the video of the valve train:https://drive.google.com/file/d/1p2JFmbaROMmPvw9vjiMblkz887hryG4g/view?usp=drive_link

Thanks in advance.
