I am replacing the head on my 1985 Ford 1310 and ordered a re manufactured one from Weavers Tractor Supply. While switching everything over to it I noticed the area where the injectors go look different.

The original head is a N831 and the rebuilt one is a N832. I have new injectors to put in and they look exactly the same as the old ones. I have posted a pic of the two different heads below. The black head one is the new one, the blue head is the old. The old head seems to have a cup inserted into the injector port. Did whoever rebuilt the head forget to put the pre combustion chambers in the new head? If so, is there a way to remove the cups and put them in the new head?

I should add, the castings look different on the heads too. There are freeze plugs on the new one where there are none on the old. Not sure if the new head is just an updated style or the wrong head. You can see in the pics the black one has a freeze plug where the "85" is on the blue (original) head.

Thanks for any help!

Nope. I bought it used. I have found the 831 head was used on the Shibaura S753, according to All State Ag Parts catalog, as one of the options they have listed for replacement heads is the N831.
