U shudn't need to worry about temps (IAT or underhood). I have the old Dynatech's too and shuda got the ceramic coated. I ended up wrapping mine, but only the first 12" from the heads. If u wrap them all the way, ur likely to crack them - especially with ur winters. I wrapped mine to get temps down and stop burning wires. R/

If I were you, first thing would be get Nelson to send you a PCM tuned for the addition of your headers and get him to disable your rear O2s. Then you can see where you stand. I would not want to have just the light turned off, then you wouldn't know if the problem is fixed until you pull codes again, or try to get an inspection.
