These rings are new old stock that have been poorly stored for many years and in a really poor condition if you  buy them and they are not to a standard you will except return them immediately. They have been measured without the aid of specialist tools  and sized accordingly we maybe wrong. You can adjust the end gaps to suit the bore size but usually it be from one size oversize only. Look to get about 4 thou per inch of the cylinder bore end gap in your rings as you would normally when you fit piston rings, if you don’t know what I am talking about seek help
