Myself and my builder haven't been a fan of resizing oem GM rods for ARPs as it's yet another place for margin of error, and no one really knows of stock rods are safe to resize that much. I mean you're taking away metal for a more "robust" fastener.

For our RPM/power levels I think it makes more sense to just buy two sets of oem rod bolts: one to check/set clearance and one for final assembly.

Once you're at the stage where you feel like you need ARPs for rods, time for better rods that were made to take them without modification.
