I'm having to replace 2x rods due to a minor fail, the replacement rods are 6 grms heavier than the originals on the big end. The machinist has suggested I fit washers to the original rods to make up the weight. Do you think there's an issue adding washers? Rod washers from ARP are 0.061 thick, thats 0.061 less thread engagement with the rod bolt. Am I overthinking this or is this acceptable?
