Definetly replace the rods. Because of stretch it should be set up with more deck clearance, so you might check that when you change them. They are really only for engines with frequent (read race)teardowns. That's why it's easy to pick up used ones from many of the Pro racers as they try to offset the cost of replacing rods every few runs. OR.. you could keep them and listen as that tapping noise grows ever louder and the piston conforms to the combustion chamber shape, it's all in what you want.
