What are these?

[knucklebuster]

I just got my head back from the machine shop along with a box of random parts and bolts that came off the head. I have these, and im not sure what they are or where they go. Any help is appreciated

looks like fuel rail spacers

Yup. Missing a black piece tho and the black part goes up.

That is where they go, to hold up the fuel rail.
