Was the head milled flat prior to reinstalling the new head gasket?

Not sure this^ qualifies. Did you check whether it was level with a precision straight edge?

unfortunately, no this is not the proper way to surface the head. but before you take everything apart can you describe what is happening whe it over heats? it could be as simple as the coolant not being bled properly after the hg replacement.

does it overheat at idle? when the car is in motion? after 2 minutes, 20 minutes, 2 hours?

don't give up. it's a Honda. It can be fixed.

With the car running and the rad cap off does the water looks like it's flowing? Now that you have all the air out it should be easier to tell.

You've got air in your system. These engine's are super sensitive to it. I had the smallest vacuum leak on 1 coolant line going to my IACV, & it gave me hell.

Isn't it impossible to have a vacuum leak in a coolant line?

Well I'm not having the same exact problem as you but i'm having a similar problem. One day my car's temp guage was sky high, Pulled over realized I had no fluids in my radiator (strange cause I just did a tune up a month prior) refilled it fine no more problems but something told me to check my oil, realized that my oil was really low. ( strange again cause I just did a tune up a month prior) ever since I put more oil everything is fine I've been checking both radiator and oil level 2x a week and nothing is dropping. and no more over heating!!
