yes, NOT like a kingpin [which are grease cups], the dome goes in, and you don't want to pound on the center of the new one or the cup will deform and leak, if the old ones were in so the dome was out, they were done wrong, more reason to change them all!
like on this small block,
drive in like so and they're
installed ... and if you haven't bought a set yet, get brass ones
