LT1 and DFI, How many O2 sensors?

I'm going to be using DFI and DFI harness to control the LT1 in my IROC. I just got Hooker Long tube headers and need to install the O2 bungs, but I need to know if DFI will use 2 O2 sensors (1 for each header) or just the one like a regular SBC DFI uses. Also which header to install the bung onto? The drivers side or the passenger side?

it needs two ....the actual locations should be one on the driver side header or manifold and one on the y-pipe.

Remember Matt, I'm using DFI, NOT the stock PCM and Harness.
