With an internally balanced rotating assembly, you will be OK with a clutch/ flywheel and a balancer with zero /neutral balance.

However, to be on the safe side- take the whole assembly for a check. My 2 cents...

As Rick, I did the flywheel in wheel balancing machine. However- I sent it to the engine shop who checked it. Not very expensive job. 200 euros is what I paid.

Good thing you're getting the engine back together, Eljaro.
