Do the oil seals on a briggs lawnmower engine sit flush with the housing?

Briggs engine model 285707

It's a 12.5 (i think) HP, L head engine. My first teardown and rebuild... do the oil seals (one on blade side, and one on flywheel side) go all the way to the bottom, or do they sit flush with the engine housing at the top?

Here is a picture of each seal sitting flush with the engine, and hopefully you can see how much room is left underneath it.,SNC99lb#1

They don't necessarily fit flush and they don't necessarily bottom out... just as long as they are square or level in the bore, they are fine.
