Changing the starter... you have to take the H-pipe off to do it. So I have just the factory shorty headers on the car. Can I start the car for a minute to make sure the starter is working ok before putting the H pipe back on? I know it will be super loud, but will it do any damage? The pre-cat O2 sensors are right there at the end of the headers. Won't hurt them, will it?

It would, but it won't hurt anything. It's not like you're going to sit there and crank it right? You're just going to hit it for a second to make sure the starter works. By the time you get the car back together to drive the trace amount of fuel sprayed in by the injectors will have evaporated.

You wont hurt anything by running headers only. My buddy and I drove his 64 1/2 mustang about 30 miles to the muffler shop that way.
Granted, different motor... older motor, and no cats obviously. It will be fine for a couple minutes. I would just keep an eye on temps and where the exhaust is going and what it is heating. It will just throw a couple codes for catalyst deficiency (since they wont read correctly) You wont have it on for that long anyway.
Besides, you gotta do it once. Do it for your neighbors =)

Yep, just floor the pedal and crank on it, it won't start.
There's an algorithm in the computer for clearing a flooded engine that shuts of the injectors when you floor it and try to start it - similar to
how we cleared flooded carbutrated engines - lots of air, no fuel.
But running it a short while will not hurt anything. Should not even set an O2 code if you run it only, say, 30 seconds at a time.

Just watch the heat if you let it run more than just a few seconds.
