Aluminum 317’s would be better for the 4" bore, plus they are like $150ish on ebay. Sodium valves are useless on this build, it will never see high enough RPM to benefit from a lightweight valvetrain.

there is no reason why it couldnt see 7-7500rpms with those sodium filled valves, ported oil pump etc.
