If you want to run stock rods, look for a "B" stamp or an "X" stamp on the rod cap. "O" or no mark at all have less nickel in them. Take the time to remove forge flashing off the beams. "Beaming the Rods" is what this commonly referred to. If you wish to go a few bucks more, have them shot peened before reconditioning. This will had some extra strength and I feel you'll be happier. It also takes the sheen off of them. Shiney rods collect more heat than dull ones. Definitely run a good bolt like ARP.
