ahh ok so carbed, the bronze lines off the manifold are your air lines and the water lines are off your head.  so not to get them confused reach in there and take a peak so you know for your own reference what is what. 

so the air lines your taking about are for the EGR system allowing unburnt gasses to recirculate and be burnt up again and on the california emission models i believe have the smog pump hooked up to the manifold for added fresh air to burn gasses once they reach your catalytic converter.  if you have fed/can. emissions its just tubing for your EGR and no smog pump but us cali guys have both.  your water lines for heating are hooked up to your cylinder head.

now for the emissions unless your coming to california you are fine with federal/canada emissions set up.  if you have the cali emissions set-up and are moving to colorado, shoot your ahead of the curve with added emissions. they might  you as a tree hugger  and behind your back for being so clean or  worship you, who knows.  good luck
