Any difference in heads off a h23a and h23a1

Hey guys I got a h23a in my life and I have to swap out the head because two bolts broke off in the head and I have a h23a1 motor as a spare. I broke off the snap-on screw extracter in the head as well so I give up. Any thing I need to know or they swap right in? I know the a is jdm and the a1 of usdm thanks -anton

Its the non vtec engine i was told there is a diffrence in bolt pattern but i wanted to double check on that. I am going to have the head rebuilt and i dont want to rebuild it if it wint bolt up. But i am very certain it will. Just want to be safe then sorry
