The forging "dimples" on the big ends you can see just above the big end cap in the photo below are a place you can remove weight without weakening the rod in any way; reducing/removing these also allows you pass the big end down the bore when building up your motor with the block already bolted down. If you can't get enough reduction from the dimples, reducing the size of the flange on the big end cap slightly is worth a gram or two.

once you have equalised the big end weights, there shouldn't be too much to remove from the small end as there is relatively small weight there anyway. Start equalising here by grinding away any forging flash at the small end; you can see this in this photo where I'm balancing a set of non A7 rods.
