The older head types did not have as good of atomization of the fuel, so it is not an uncommon 'fix' to run two plugs per head to improve complete combustion of the fuel ... Panhead and Shovelhead in particular ....
I think Sniper said that head is from a Shovelhead ....

Cannot believe that the owner had the thing in his hands (and his mechanic who assembled the thing) ... and did not notice the error ... WOW

I put it together today and managed 50 psi out of the front and back cylinders after adding oil through the spark plug holes.
After setting the lash and adjusting the S&S carb I managed to fire it up with one compression stroke!
I was pretty proud to have managed a fire up and finished the bill with only 3 hours labor and new gaskets for the intake.
This thing came to the shop without a seat or a dash so the customer got called to bring his trailer and get it off our inventory.
