Ticking noise, 383, can't locate the source

Pulled the cover, pressure plate bolts all tight, clutch, bearing, fork, flywheel all look fine. Ran it, tick isn't any louder, spinning true.

Pulled rockers/shaft. I don't see anything that stands out. Looks like normal wear, don't see any cracks.
Shaft looks fine.
Pulled pushrods, all look fine, none bent.
Valves/springs look fine.

Of course, I am not familiar with what everything should look like with normal use, but nothing slapping me in the face.
