1600HP Rings and ring gap?
If you really want feedback here, there is absolutely no way for us to even remotely answer your question, with out providing us with bore size, piston design/material, piston ring design/material, fuel, expected power, cooling system, crankcase evac system and the list goes on and on....
Because you didn't provide that, you probably need to seek the help of a actual engine builder and not a forum that caters to about 90% of the community here that don't even make half the power you are shooting for.
Just being honest with you bro.
