Yup, when I checked O2 on primaries, I have 2 lean cylinders and 2 rich cylinders so O2 on collector averages everything out and says things are OK. In a SS application, there is the ability to possibly modify the intake and improve the situation, a lot tougher in Stock but maybe some creative corner jetting might help?
