I think this is what I'm going to do as it makes sense to get all of the cylinders exhaust passing over the O2 and not just the one cylinders (just in case that 1 cylinder is off for some reason).
Anyone know where I can pick up a foot long O2 extension for each bung? Do they even make these things? 
I'll end up plugging the upper bungs with plugs or old O2 sensors. The SCT programmer up here at steeda.ca said he normally turns off the back O2's anyway so I shouldn't even need MIL's.
