Can I suggest you loose the bolts and discover a significant improvement in stiffness of the mounting and increase in the natural frequency of vibration of the pier + EQ head ?

EQ heads need polar aligning, but they simply do not need leveling.

The EQ head/pier combination however works much better when it is rigid, rather than acting like a spring
I've often wondered why people do this too. All that money on expensive mounts etc, then sit it all on 3 extended bolts (usually around M10-M12 diameter). In structural engineering design of buildings we'd call that a "soft storey."
