Project: Iron block 5.6

I'm starting a new thread concerning my project to build an iron block 5.0 engine since it's progressed from concept to actual construction. I am removing about 28g of weigh from the pistons by machining the tops down to accommodate the longer stroke. This will require the engine to be rebalanced-no big deal-it's done all the time.
The connecting rods have large balancing pads on the big and small end-much larger than required to weight match the rods. Since I'm rebalancing anyway my thought is to lighten the connecting rods by removing the excess balance pad. Not sure why there is so much excess-is there some reason? It seems to just add unnecessary weight to the connecting rod. Reading other engine building forums it seems common practice.
Also check out these cool Megasquirt trigger wheels I found on Ebay:

The seller also has the bracket to mount the VR sensor.
