Can anyone confirm is the Tecumseh Ring set P/N 27565 is correct for the HK25/30 engine?

I found an old thread started by Mt Bonnar called "Kirby H4-4A engine rebuild" where he obviously finds a ring set, even puts a picture of the rings and box in the thread. I have zoomed in as best I can and I think the part number on the box of the rings he used is 27565 but I am not 100% sure.

Any help is appreciated.
