O2 sensor question
I’m installing long tube headers on my 94 f150 5.8. The headers I’m putting in need to have an O2 sensor bung welded in. My question is would I be good to keep the 1 O2 sensor and weld it into the collector valve on my passenger side header, or do I need to weld it into the crossover part of my h pipe? Or do I need a whole other O2 sensor for the other side? I’ve heard different answers, that’s why I ask

In the passenger side collector works great, I verified this with testing when first installing longtubes on my '90. The reason this works is because there is only 1 fuel map for the whole engine and injectors are fired in batches which span left and right engine banks so as long as the sensor is sealed inside the exhaust it doesn't matter how many cylinders it is exposed to.

My pacesetter long tubes, could not put O2 in passenger side because too close to E4OD. The bungs for O2 already there.
Speed density, works fine with O2 only in one side, for me it was drivers side.
my future plan is to have a cross over tube like stock, don’t have true duals, driver side header curves over to passenger side, like stock y-pipe
