did you hook back up your o2 sensor?

Usually O2 sensors fail after a header install. You can scan the PCM to see if it stored anything relevant to your problem. I would break in the headers a little then replace your O2 sensors. Also check your wiring to them and make sure it's not contacting the exhaust.

Front and rear are not interchangeable. They have different connectors for that reason.

Because it is in open loop on cold starts and doesn't look at the O2's. I'm 90% sure that your problem is the O2's. Like I said, I don't think you can't switch front to back because they are different.

Good call Lyle. This is a good post. I would look at the things Lyle suggested, they are all good things to check. It does sound like an EGR or an O2 sensor problem to me.
