Why would a 1991 Acura Legend ac still blow hot air after changing the compressor is it related to a head gasket leak?

If you're fairly certain the compressor is properly charged and in good working order, then you must determine if your AC/Heater Control Panel is functioning properly by moving the thermostatic control knob back and forth from Hot to Cold and listening for the compressor to kick on. Often times when a new blower motor unit is installed, two identical wires (one wire goes to the Remote Trunk Unlock Button) get crossed and plugged to the wrong connectors which will blow the control panel each and every time; the Control Panel will then need to be replaced. Not sure if you can purchase a new/refurbished Control Panel, but they can possibly found on EBAY for $50-$120. So if your AC vents are blowing hot air no matter where the thermostat is set, then this is possibly your problem, considering your compressor is working properly.
Easy install, but make sure those two wires are in the proper order first.
