Dave;

I had a similar experience during my recent engine (new cam) refurbishing.  I 
too used the Haynes book.  I had taken the old oil pump out (like yours, not 
original equipment as mine was replaced a short time ago) to examine it for the 
casting flange, and to check the rotors against specs.  Once I had it apart, I 
noticed the mention of the chamfer.  My oil pump had no noticeable chamfer.  I 
assembled it the way I thought it should go based on the light scoring on the 
rotors.  Whether it was assembled right or wrong was on my mind right up until 
I cranked the engine over without the spark plugs in order to build up the 
initial oil pressure, it took a while and I got panicky, thinking the pump was 
to blame.  Finally the oil pressure came up.  My advice, forget it.  I'm 
willing to bet that the later pumps do not have any chamfer. and it doesn't 
matter which way the outer rotor is installed.

At any rate, prime the oil pump by cranking the motor over without the spark 
plugs installed.  Make sure your battery is well charged.  Continue to crank 
until your oil gauge registers pressure.  You may have to crank for 1 to 2 
minutes.

Good Luck, go have that beer.
