This depends on how far out of spec the rods is and whether material was removed from both the rod and cap or just the cap. So to answer you, it could be anywhere from several thousandths down to a tenth or two. I feel that checking/correcting bend and twist is as important. Problem is, some shops either don't or can't do this.

I would like to say using an aftermarket forging will cure all the problems associated w/resizing rods. But in this imperfect world we live in, even new rods can be out of spec, so they should be thoroughly inspected before use.
