Dead hole. What’s the next step

Well, China freight was out of leak down testers so I amazoned one. I’ll do the test when it gets here ....BUT ...I have a lead. Bear with me
Rockers still removed
did the bongo test. #4 bongo’d so as to learn the sound. And fan spun.
Moved onto #2. Same EXACT sounds as #4. The fan also spun just as much as #4
I also spun the valves before and after bongo test
Next test
made sure throttle was open pressure at 90#
No air out of carb
Coolant level did not move
No air out of exhaust manifold
I cut fingers off a rubber glove, taped them over dipstick, breather, and pcv. They did not inflate at all.
Now remember back to when I said I did the compression test and got 60....then removed rockers to check the pushrods. Then reinstalled and got 0?...

could this cause it. Could this lifter be cause of the exhaust valve to stay open enough?
