4-1 header/Dual o2 senors? Possible...

ASSISTANCE Hybrids & Advanced Aftermarket Engine Performance

So I was thinking about buying a 4-1 header from a friend for my b16 xsi teg. Problem is is that the xsi engine takes two o2 sensors, 1 for 2-3 cylinder and 1 for 1-4 cylinder. With a 4-1 header its impossible to get both cylinders with 1 o2 sensor. So now the question is can I just put one o2 sensor in the #2 cylinder and and the other o2 sensor in the #4 cylinder? Will this make the o2 sensors read wrong?

^^ Exact same thing I did with my B16. Worked like a charm, and never threw a cel.
