Mark, Do you own one of those cheap infrared pyrometers from Harbor Freight? Much better than wetting your fingers and touching the headers? They work great for header temps and usually can pick them up for $14 on sale.
I don't...I see them in Lowes every time I'm there on a Lana project and think about grabbing one....but they are a lot more than $15 at lowes. I wonder what you get for the extra money?
I know we were using one at work and to get real temps we had to paint the surface with a paint that has a known emissivity....but I guess I that doesn't really matter for pipe that you just want to know if they are hot or not (which used to be a web site were you rate pics) so the exact number isn't important. The real problem would be getting it reading on the front pipes....the only way to see really see them is from under the car....maybe a mirror.

I can also get my hands on an Innovate LM2 if you think it would help? It only reads one WBo2
I have 2 or those now in the 2 bank collectors but also now have the code to get the ECUs internal WB controllers working so in theory I can use the ECU to do the WB reading and read up the the 2 LM2s.
I think my first step will be to actually look at what I'm getting off the the NB sensors and see if I can pull out the cylinder data the way I think I can. If that works I'm good for now and can switch the WB control to the ECU when I get time. If it doesn't work I'll need to install the NB sensors in the pipes and use the CAN expander to read them instead of MAP or get a second CAN expander maybe....and get it working as I haven't done that yet.
