Rick good luck with the troubleshoot. I hope it's something simple.
I don't know what the coolant plenum looks like between the two cylinder banks but is there a way that there could be a restriction on the overheating side?
Is this something that can be checked through the thermostat and restrictor plate opening?
Again good luck with the troubleshoot......
