Default difference between PM9-1 and PM9-4 heads

I have a 92 civic that I use to drive back and forth to work for gas mileage purposes. A few weeks ago a chunk of one of the valves broke off and in the process scuffed the head up. I am looking at a rebuilt head that supposedly came off a B15D7 like mine. Mine has PM9-4 casting numbers on it and the one I am looking at possibly buying has PM9-1.

Is there any difference in the two heads?
