Yes. I've never done it, but reshaping the rod bearings is an important part of the process. There are more experienced people here on the barn that will hopefully add more comments. Note this only applies to floating rod bearings. People have mixed up the instructions before and tried to do this with insert rod or main bearings.
A thought: Some bearings are oversize on the outer diameter, to suit oversize rods. Make sure the bearings are sized to suit both the crank and the rods.

You can check the thickness of the bearings by measuring the crank diameter and the bore of the rod and doing some sums to get the bearing thickness.
