I also found it weird, but i read it during a reassembly on the first 993 engine ive rebuilt just last week. Remember 993s are the only road car engine (that i know of) that use bolts in this area, not studs.
I only sealed the outer bolts as they are through bolts, the inner row are blind holes.

see the installation note 1
