Probably it's a weeping frost plug and corrosion is forming there or coming out there. Judging by the look of the oil filter, this engine has not had the best maintenance. When was the last time the coolant was changed and flushed?

Just get a small piece of sand paper and clean up the remaining rust in those frost plug holes by hand. Use a bit of sealer like Permatex on the new frost plugs.
The rods that often are found in the water jackets either loose or still attached were put in to hold the sand "cores" when pouring the molten iron to form the casting at the foundry. They are benign.

Definatly flush that block good before installing, and with something besides just water. I can see a clogged radiator in your future.
Edit: Also I believe there is another plug behind the flywheel. Someone may verify. Better to check now.
