Balanced Crankshaft (Need Help !!!)

The way I always understood it was the forged cranks were internally balanced and the cast cranks were external.

I talked to the guy that did the balancing and he said that he tried to balance it with the weight in the balancer and the flexplate and it was around 80 grams off, he took them off and they were closer to balance.

I guess as long as it balanced out I'm okay. Right?
