Some folks add counterweights to the model A crankshafts. The early B engines didn't have the counterweights yet so they vary too. There were different forms of counterweights in the B era as well.

Don't be afraid to use any of the model A crankshafts. Many have pounded pretty hard on the early types and reported little problems with them. Most folks that run them hard are fully aware that something can happen to any of them. The center main is likely going to wear out before the others just because the design only had the one central main journal. Flathead V8s can have the same problems.

The early connecting rods that has the X-shape probably should be retired. I've heard of problems with them.
