Just curious if it's something that is a requirement no matter what the situation.
The manchine shop will check the cylinders for wear. All blocks are going to have a tapered wear= where the rings ride up & down in the cylinders, so more than others. To do it right you'd want the machine shop to figure out if it just needs a cleanup hone or bore & hone & oversize pistons & rings. Then you'd want them to resize the rods & hang & align the pistons unless you have floating pins. For a basic small block chevy kit it'll come w/ cast pistons,rings, bearings= rod/main, oil pump & a true roller chain. Then the machinst w/ say like= You need a .030 over pistons & .010 under mains or rods or both. Then you order the correct clearence sizes. Then the fun begins, grab a plastic gauge kit.
