I agree w/ post #2. I would get an IR gun (cheap at HF) to verify temperatures and useful on many cars. Mine gives good agreement w/ the dash gage in my M-B and the T-stat stamp. Of course, Dart dash gages have no numbers on the tics.

In this day, it is simpler in the long run and much better to install an O2 sensor in the exhaust to determine rich/lean, so at least have a bung welded in when re-doing the exhaust or if you have the pipe off. I put two bungs in my cars so I can install a wideband O2, plus a regular on/off to verify calibration of the wideband. To get started, you can get a cheap rich/lean indicator (~$20 used ebay). Widebands are dropping greatly in price, so can screw one in the same hole later. Much better than trying to judge from viewing spark plug tips, over-heating, max vacuum, etc. I wouldn't try tuning a carb today without one.
