The Superior Millennium cylinders I’m fitting need the piston rings gapped.

The PDF’s available online don’t specifically mention my C90-14-F engine, they kind of jump over it from A65 straight to O 200.
But - the service letter L05-09 B covers the part number on the ring’s box of SA2000SC( sort of), as it doesn’t have the suffix SC)

I’m aware the O 200 is mostly the same engine, and only the exhaust spring is different on an actual O200 cylinder.

Anyway - that service letter specifies :
Top ring 0.023 to 0.036 inch.
and implies : 0.015 to 0.028 for second
and implies 0.015 to 0.028 oil control.

Anyone know if that correct ?
