I proactively replaced my OEM balancer when doing a H/C 3 years ago with another OEM balancer. My OEM balancer had a weight in 1 of the 12 holes used by the factory to fine tune the whole rotating assembly. You might inspect your existing balancer for weights and see if any were used. If so, you are actually creating an imbalance by putting in a zero-balanced aftermarket HB that has no provision for those 3 and 4.5 gram weights.
Here is my thread on the topic, along with pics.

Mine went bad I replace with an SLP with slight underdrive and new GM bolt. Overall has been great for 5 years. Only wish the SLP was lightweight like some of the others to free up rotational mass.

If you have no intentions on tracking the car or adding a blower sometimes down the road then a Powerbond Balancer with a ARP Bolt is perfectly fine.

I have had my balancer off maybe 3-4 times and never removed the rack, I just push it over to the passenger side and move the driver side tie rod up and out of the way to clear the balancer and front cover if you are doing a cam or replacing the cover seal... you can change the balancer without removing the radiator but you have to be cautious as to not damage it... if you are going to do a cam then you will need to remove the radiator
