I think the dowl pins are what the small ring of the plug hole gaskets 
go around.  see photo attached ( I hope it worked).  they help hold the 
plug hole gaskets in place.  they are never removed. 

there's no tighteing pattern mentioned in the book.  I think Mike was 
just referring to standard cover tightening procedure.  I start at the 
middle and work my way out in a spiraling/crossing pattern to the outer
