Anyone with headers want to pontificate a reason why my car would throw both lean and rich codes?

Granted, my car has a lot of codes since the header install. And I deleted my smog pump too so that added to the mix.

But tonight I removed my old CVV from my manifold and just ran the codes for giggles. This time I have p2272 (02 sensor bank 2 stuck lean), but I also have p0175 and p0172 (Banks 1 and 2 running rich). So how can it be lean and rich at the same time?

I know my 02 sensors bungs were in such a way that one 02 sensor is mighty close to the other header pipes, could it be ruined as a result?

Should mention it has been close to a month with the headers, car still runs HARD, idles perfect and has no driveability issues. I have not reset adaptions since I installed the headers either.
