There are no balance weights on the crankshaft vibration damper. The damper is not keyed to crank snout and can be re-installed in any position relative to the crank. If there was any external balancing needed, they were added to the flywheel at the factory, and must be reinstalled in the same relative position when the flywheel is replaced. Run a search; this topic was discussed at nauseum for several years on this forum.

So best practice in the case where you find a weight in the balancer during replacement would be to replace with a factory (or powerbond) balancer ..making note of the position, and transferring the weight. If there is no weight in the existing balancer......install whatever you like and enjoy.

Mine has balance weights added. Thought that the Z06s had a different damper than the LS1s lighter. The center part on my oem one is aluminum.

Not good advice! Balanced is balanced. The HB comes from whoever manufactured it as a balanced assembly. If it has existing weights, they were added to that unit to balance it, and are only useful for that particular HB. I agree it can be mounted anywhere radially on the crank. It is balanced and radial location means nothing. DO NOT add or subtract anything, or you're asking for trouble......

I can tell you that the GM service manual, at least for my 2000 model, does contain a few errors here and there. If an assembly is balanced, it can be clocked in any position radially. Might help to think tire balancing here. Once your wheel and tire are balanced as a unit it doesn't matter how they're oriented on the hub. It also doesn't matter (balance wise) which of the 4 hubs it is mounted to......
