Yes, a production crank is balanced as a unit using "target bobweights" which will be close to what you'll have. When we talk of having the engine "balanced" today we're talking about the dynamic balance, where the actual rods & pistons being used have been assigned positions on the crank, and the precise weight of each assembly is considered in the "bobweight" for each journal before spinning the crank in the balancing machine. That's why Jerry says the balance won't be an issue if using the original rods/pistons. There are lots of magazine & tech articles on the web that explain the balancing process, and why things are done the way they are.
