Problems after header install
Get an LS1edit tuning, and if you have aftermarket MAF ends, put the stock ones back on. Also, any chance you damaged the filaments in the MAF sensor in the process of all this?
You defintiely need the LS1edit tuning to eliminate those codes... delete EGR, delete the rear O2s, delete AIR, and while you are at it, delete CAGS. Even if you weren't throwing those codes, headers would still have a tendancy to make the engine run rich... add that to the codes and I think you have a big part of your problem.
As for teh MAF malfunction and the left bank codes... your guess is as good as mine. All I can say is you may as well check and make sure everything is tightened down with no leaks.
