I had a rattling noise too. After a few days, it settled and went away. Believe the cause was the same.

Headers installed. The power is back and after a few pulls, no misfire. She's young again!
I'll run the car for a week, if the misfires do not return, we can consider this case solved.

She died on me today as I took her to redline in third. I was on the highway, airing it out, hit the rev limiter and got the same misfire code/symptoms as before. I'm thinking in my head that the problem isn't solved yet. I cycle the ignition on and off, but the problem doesn't go away. It has gotten worse. It feels like about 3 or 4 cylinders are completely out, very difficult to start due to the missing cylinders. I was able to limp it home and try to read codes, but I don't get anything but the cyl 6 misfire code.
I'm wondering if my timing jumped? Fuel is good, I *think* ignition is good. I need to do a compression test next...

I found the root of this issue in the form of a broken keeper on cylinder #6

It was probably opening fine...the closing part is questionable.
