Sorry. Big-port piston rings are all the same 18mm pin, 20mm pin and 8.0:1 GZE pistons being alike, while small-port piston rings are different. The smallport high compression 4AGE and 8.9 GZE pistons rings being alike.
Basically once they went to a smallport head the piston rings changed also. So bigport piston rings wont work.
