Will swapping harmonic balancers cause any issues ????

My engine has had the rotating assembly balanced. It is a 340 with a steel crank ( internally balanced ). The balancer I bought is a decent one but I have considered using a something like an ATI balancer. Will swapping on another balancer change anything? Would going from a stock style balancer to an ATI be an improvement. This is a street car that will see an occasional high RPM blast up around 6400 or so.

Good question..I'm thinking about swapping to a fluid dampener to help the engine a little.
