How many/ which gases does this tool measure?

Has anyone actually used this, and does it perform well enough to go by its measurements before smog so I can tune and then smog same day if possible????

Can it meassure HCppm, CO%, CO2%, NOXppm? This is requirement in Mexico.

No, it is strictly for CO%.Cheers!

Can this be used to test the radiator for head gasket leaks?

No, measures only combustion by-product CO or Carbon Mon-oxide. Used to adust or test fuel mixture.
