over the course of about a 180 mile trip, i am loosing a little bit of coolant. (like a pint or so) more like i am adding coolant , but i cant find where its going. well, i have a pretty good idea where its going, but wanna be really sure before i dive into this thing.
did some searching and can answer what i read -
no white smoke out the tailpipe.
no goo under the oil cap.
oil looks good, i have to add some like i always do, so i dont think its heading down there.

i have the equipment to do a cooling system pressure test, but honestly dont know how to do it.

i really wanna make sure its the headgasket before i jump into this. by the way - 22re.

what else can i check to narrow it down?

To do a pressure test, take the rad cap off, connect the pump and simply pump the pressure tester. You will find out easily where the leak is from if its external.
