ls1 rod bolts

Agreed... you SHOULD resize them, as most aftermarket bolts have a slightly larger knurl or shank area. Do this as a test- if you cant lightly tap the bolt in all the way, it needs resizing, as the bolt will push material toward the rod pin, which will slightly squeeze the bearing ends.

Honestly, have you called ARP yet? I had heard that they make a replacement bolt that you don't have to resize, but I have yet to install any. I like to use the Wave bolts, or Katech rod bolts- and true the rods at the same time.

Either way you smoke it, replacing the rod bolts is cheap insurance, as the factor LS pieces are not the best.
