I want to swap to the KB237's and am concerned with how much rebalancing I'd need to do for them?

Stock, dirty 400 rod and piston. 1816 grams. Stock, dirty 440 LY rod and piston. 2??? grams. Lightend, 440 LY,s and KB 237/040 pistons. 1803 grams. 440 Source H rods and KB 237/040 pistons. 1748 grams.
