As you reduce the ring size from stock to something smaller it will reduce rpm's. Smaller ring = less rpm,slower holeshot and faster top speed. Larger ring = more rpm, quicker holeshot and lower top speed. The rings are used to tune rpm's to a particular prop pitch or when the seasons change for example when summer heat causes rpm's to drop, you can go to a larger ring to regain lost rpm's and avoid removing the prop to have it repitched.

i think the oem nozzle have big exit ring but closer exit to the pump cone.
something like riva nozzle with 85mm and cone spacer.
i just want to know what nozzle its better at the same rpms, riva (long) or stock one (short)?
