The odd and even relates to the firing order. Odd is 1,3,5,7, even is 2,4,6,8. The O2 sensors do not matter. You can install them in either side.

I can only assume you drilled a hole int he collector, welded in the O2 bung, and installed the sensors?

Yes, I drilled a hole, welded in the O2 bung, and screw welded lambda monitoring shows continuously 1.0. Idle speed 1000 RPM
