In my experience you don’t want to cut that bridge out. That’s what let’s you run a huge exhaust and not snag a ring.
On really high effort snowmobile engines you need to actually chamfer the piston edge as well so it does not scuff the port.
The new ring idea is very interesting but i think it will still scuff pistons. There are different forces at play driving the system with the crank instead of the piston
