You'll be fine with those ring gaps , if the motor is gonna see any power adders then the rings should be gapped accordingly , those ring gaps seem pretty loose for a 4.070" bore anyhows , i would be incllined to gap the 2nd ring .002" smaller than the top ring , those iron rings will open a tad anyhows , if the motor does'nt see any high RPMs then ring flutter should'nt be an issue anyhow.
