Default Is this cause for rebalancing

My 5.7 was balanced before it spun a rod bearing but to save money on crank machining I used another stock crank which is what I was using already same pistons same rings and two rods were ruined so eagle had my machine shop weigh them and they sent me two rods weight matched to my other 6 so does this mean I need a rebalance I mean not trying to cheap out I'll pay if needed but machine shop hasn't mentioned it yet so I wanted to see what y'all think

Since you're using a different crank, I would have it rebalanced.

The crank needs to be balanced to the same bobweighg number as your original crank. If it's the same, your good. If not, just take the crank and have it balanced to your original bobweight. Shouldn't cost much as they're not doing all the rods and pistons again.
