rotating masses

[383 chev]

Hi hows every 1?
My ? is Ive been running a 383 for 4 yrs now. Last fall i broke two pistons and cracked the block. So this spring i bought block and pistons from local machine shop. Last yr. I had 5.7 rods. this year i have 6.0 rods and i didnt have it rebalanced. Then Ive been reading around some cranks say for 5.7 rods an others for 6.0. Should I have it balanced or is it fine?

yeah it is the same crank. and it was balanced to the 5.7 rods
