Default O2 Sensor & CMi's

I am getting ready to go EFI. I am going to have a wide band O2 Sensor. Does any one know where it needs to go on the cmi etops? If you had it done who did it?

I have seen it mounted in one of the rear cyl. 7 or 8 right above the bend.

Many of the single O2 sensors are mounted in the inside of the elbow or collector. If sensors are to be used in each primary tube they are about six inches from the head flange.

Getting only one sensor. I was thinging that it was to go in the collector after each primary tube come together, somewhere in the elbow. I just did not know top, side, underside or what. I had never thougth about in the primary tube.

Getting the welding done right on a primary tube would be dang near impossible after the headers were built.

You almost gotta put it near a joint or flange, where you can get the tip of the Tig torch in there to it.
