I not able to view clip but it is possible that EGR is stuck open. That will make it idle rough. your description sounds similar to my experience.

I'm 100% sure its a burned valve.
Did the old dollar trick:

Stick the dollar on the exhaust pipe, and if it sucks it in and blows it out repeatedly, its a burned valve.

In that case I say do a compression test, it'* about as easy as changing the spark plugs. This will tell you which valve is bad. You can then pull the head and change the valve. If you need a valve, let me know I have a bunch, as I sure so does Bill.

A guy from here in the for sale section, 2000bonny I believe, has offered me a complete engine for $150, which i can drive up and pull everything off of, heads included. I wouldn't mind putting new heads on here which I can port to remove casting defects from and have the peace of mind of knowing that I won't have to deal with another possible burned valve somewhere down the line.
What do you think?

You wont know that until you have it off the car and inspect it. Getting a valve job would be a wise choice. But then your pulling both heads. If your going to that point, I suggest pulling them both and getting a valve job. Or, find another set of heads, and swap them.

A valve job would cost me $240 plus parts, where each valve and guide that needs replacing is another $40 added, plus seals and etc.

Valves burn when they don't close all the way. They need to seat to give off the heat, if not, they just get hotter until they burn. The valve could have been bent, or dirty causing it to stick. But $150 is a good deal for all the parts.
