"The frequency of the noise coincides with the light pulse on my timing light"
This would indicate Cam speed, not crank speed. I have had flakey lifters do this before.
When Packard built Merlin engines, they were test run, disassemble & inspected, then re assembled & run again.
What a great way to spend the day!
Best wishes.
