Here’s a sequence of photos taken from my ’59 10hp showing the installation of the various pieces for the seal assembly. Note that when installing the carbon seal (what you called the ceramic holder) the side with the raised lip faces down toward the block and the side with the notches in it will be facing up.
Yes, just push the carbon seal down until it seats on top of the block. Be careful, as the carbon seal is somewhat fragile.
