Thank you for all the suggestions!

Here is what I tried tonight:

Swapped injector wire 7 and 8
Swapped plug 6 and 8
Fired it up and exhaust on 8 was cold

Checked the plug on 8 and it looked wet.

Then got a different plug wire for 8 and checked distributor cap. Tried that. Same result.

Took upper intake and valve cover off again and turned the engine to see if both valves open and they did (I guess if the pushrod was bent and valve stayed close there could still be good compression).

Very confusing.

So if I have compression and fuel, it is ignition. If Cap, wire and plug are fine. I am back to square one.
Next I think I will re-do the compression test and get a different cap for it. Also will try the stethoscope test of the injector if I can get to it (8 buried sits under the intake). Any other suggestions?
