What's the remaining variable? Con rods?

If possible, swap a couple of con rods and see if it makes any difference in the deck ht. You already have reference figures. If con rods are all the same, your measurements won't change.

I wouldn't suggest shimming individual cylinders as that changes the cylinder height and affects the clamping force on the heads
