All the rods should have them. They helped lube the cylinder walls and cam but were found to be unnecessary.
If this is a SBC, those rods w/the oiler or "spit holes" weren't used after about '64 or so. They were commonly seen on the small journal SBC rods with 11/32" rod bolts. There were other engines besides the SBC that used them, too.
