Yep, understand & agree.

I still would like to know how much "piston deck height at TDC" variation is typical or acceptable among the cylinders.

Or is keeping the volume above the piston the same for each cylinder more important than keeping the heights the same (yes, these are related, too)? Thanks!

You can have a variation of a few thousands and it's not going to kill the performance of the motor.
I will say that some of the smoothest and quietest running Motors we're the ones I balanced every little thing. I have purchased rotating assemblies balanced and all, come to find out the rods very just a little...I milled the quench pads, some .048 others .046
I dialed the chambers in even by cc and material removal on one that was 4 cc smaller than the rest..and milled.
Port flow all within 4 cfm.
Quietest, smoothest running most powerful small block I can remember doing.
Many people commented on it. The .575 solid roller was stock quiet...sewing maching.

It not the end all, just better balanced all around than most. It's more than dynamic balance..its operational balance that's important as much or more.
