Believe it or not, Dave.  Making the all inclusive plate will probably be easier.  You're starting with a single plate 
of aluminum, and it is just a matter of correctly locating the holes.  The easiest way to do this is to bolt the 
housings together, brush a thin layer of oil on the bottom.  Attach a sheet of paper to the aluminum plate, and then set 
the block on top of the paper.  Every hole will be accurately located.

A thin layer of sealant around the pickup hole just prior to bolting on the plate isn't hard. Put the sealant on the 
engine.  Not the plate.

The other way, there is multiple pieces that have to be machined and tracked.
