I recently purchased a set of BBK polished ceramic shorty headers for my 1996 F150 with a 5.0 When I orderd them I was told that there would be holes in them for my O2 sensors, just like the factory manifolds. However, when I got them, the holes were not there. The place I bought them from suggested that I just put the O2 sensors a couple inches back in the Y pipe and that would be fine. I checked on the BBK website, and these are the correct headers for my truck. Does anyone know any reasons whey this would not work?
