If the back end of the crank is going to have "neutral weighted" components, the front end of the crank should also have neutral components. Staying with Magnum front stuff, you at least would now be looking for a 5.2L Magnum balancer.
If the crank is using a neutral balance at the rear, the front can be ether zero or external balance. It’s up to the flex plate to keep the external balance or be set for a zero balance converter.
My 5.9 is external balance. Stock balancer up front with a B&M flex plate for a neutral converter.
