Are these spark plugs bad?

The faster the flow of air, the less dense it becomes, therefore, the mixture will get progressively richer and richer.
Not having the O2 sensor could prevent the ECU from determining the correct air fuel ratios. When I said my guess was, that's what it was, was a guess
Unless your running the car on a closed course, you shouldn't be running without a cat
The cat soaks up massive amounts of hydrocarbons and keeps them from entering the atmosphere.

The O2 sensors measure O2 in the exhaust so the ECU can determine the correct settings so that the engine will run most efficiently.

You are wrong. Increased flow will cause your motor's fuel mixture lean unless other measures are taken. The stock ecu can compensate for small changes like intake/exhaust and atmospheric conditions (temp, humidity, etc). Twist that around.

Our factory O2 sensors are usually in the catalytic converter which filters excess fuel.

No dude, he was saying the cat filters excess fuel

Take some better pics... Its really hard to tell what is going on...
If the motor is basically bolt-on then you should be ok...
You can also take it to a Dyno for a Baseline and AFR reading...
