Try Perfect Circle Performance rings
PC 315-0029
Sealed Power

Or you can just use the JE rings.

You don't have a choice on rod length with those pistons, it's 6.385 ;)

The good news is that 4.32" is std bore for a Chizzler 440.
I used SRP rings # J10008-4320-5 which are for the 142992 pistons that I'm also using.
