O2 Sensors May be a stupid question but I need to purchase them for my swap, are they all the same? Looking at rock auto and there is a big price difference. It’s for my 2003 6.0L
Yes, there are different types of O2 sensors. There are case grounded, and then there are PCM grounded. Are you running the '03 PCM? Do you have square O2 connectors, or flat? That will tell you which type of O2 sensors you need. Flat is CASE GROUNDED. Square is PCM grounded.

Thanks, running all stock that came with the PCM. Seems to be a big price difference between the different brands, any one of these better than another or they all pretty much the same?
