Bad engine miss

I would not. I would first check compression and or leak down test. That is what they are made for--to do diagnostics without tearing into stuff and ruining gaskets, etc

Also a note about pulling wires. I recommend you do not. Instead, "rig" so you can SHORT the spark to ground. I used to work the dist. boots up away from the distributor, and insert small brads or paper clips down each plug tower, or use a very small thin probe. You can use a 12V test lamp (lamp not an LED) the spark will not hurt it. Then you can short each plug tower individually. WHY? Because when you PULL a wire, it creates a HUGE spike in voltage which can crossfire and lead you down a wrong path. Also with modern high power ignition, you can damage an ignition module when pulling a wire like that.

I also have, or used to have a pair of insulated fuse pullers for the large household cartridge fuses. You can loosen the plug boots, them get a grounding probe handy, and ease them part way off with your fuse pullers, then put the shorting probe inside the connector so it does not crossfire.
