Default Minimum wideband distance from O2 sensor?

Not finding my answer here or on other forums.

Just got my 240 back from the exhaust shop, asked them to add a bung for a wideband, and relocate stock o2 sensor as it was in the wrong position and angle.

Now both bungs are about a foot upstream from the cat, but the wideband and stock o2 sensor bungs are only about 4-5" apart. Is there some minimum separation distance required? I'd imagine if they're too close, the one further upstream will mess with the gas flow to the one down stream. Are they sensitive to that kind of stuff?
