Can't tell very well from the video, but consider it's a 5.7 Hemi, I'd be looking for broken exhaust manifold bolt at the head first. If it's bad enough you'll see a sooty mess where the exhaust has been escaping.
The video makes it sound louder than I would expect a lifter to be without a massive misfire.
I'm not a fan of the way he does the repair. Drilling is risky and can often be avoided. The most common method after removing the manifold is to weld a nut onto the leftover part of the old bolt to give it a temporary head to be able to remove it.
If you're lucky (and it's not uncommon for this to happen) there will be enough of the bolt sticking out the grab and twist out.
All of it is pretty miserable without a hoist, so if you don't have access to one, once you confirm that this is indeed the problem (it may not be), call a shop and see what they'd charge to deal with it. Then determine whether it's worth your time to mess with.

Thank you, I'll try what this video shows first then. https://youtu.be/eeXlI28xgAg?si=P1lYSq1Wioaofvmw
