What those guys said, I pretty much use ARP in everything, but that's me, as for rod big end resizing, I do it on every rebuild, did alot of study and checking on this years ago, never saw a set of rods come out of used engine that didn't need sizing on the big end , over time they tend to grow clearence at the parting line, I consider connecting rod big end sizing part of engine rebuild of any sort, this probably more than anything causes rod bearing failure, when a housing bore is out of spec, bigger, it no longer holds the bearing correctly.
