You need to weld O2 bungs here. Each O2 monitors 2 cylinders and needs to be close to the head to keep them hot enough to work properly.

^^This is correct
If you do not have your O2 sensors in the correct location your engine will NOT run correctly.

 

the one that you speak of is near the cat, right? you can't use it for obd0. you'll need to plug it and make 2 openings like shown above. or upgrade to obd1 and then use that one spot. or don't hook up the o2 at all...it will run fine, just a little rich, no check engine light
