It would be interesting to know this. Now that you bring it up I may check it when I check the washer to make sure it isn't backing out.... You got me curious, damnit....

UPDATE.
Chaz - I've got over 400 miles on these plugs now, the #3 plug with the copper washer hasn't budged. I will continue to keep tabs on it but so far it's looking good.
Bieg - the difference in torque results in what I'd say is about 5 to 10 degrees in orientation, not very much. About the thickness of a sharpie mark. This range is typically acceptable, considering using a washer is an inexact science.
unfortunately my socket slipped on one of the bolts that holds the coils in and I rounded the head.... so I gotta replace it......

Since this is obviously one of the "nit picky" threads, I'll add to it. 
If I remember correctly (from Helm's), the Primary and Secondary intake valves are not all in the same place on all 4 cylinders. The Secondary cam lobe has higher lift and probably more duration than the Primary lobe (for swirl), so it seems to me that the plug would need to be indexed with relation to the Secondary valve for each cylinder, rather than just pointing toward the driver's side of the block.

I don't know about that gernby, my understanding is that the plugs should be aimed at the point of highest turbulence within the chamber, regardless of where the valves are. I don't know where that is, I merely put my #3 plug in line with the others.....
That is very nitpicky BTW
Do you know how many washers in one thousandths of an inch increments you'd have to have in order to be so exact..... probably hundreds, and you'd spend all day long trying to get them straight. All for a fraction of a HP probably......

My mental picture of the difference between the #3 plug from the others makes me think that maybe it was really the #1 plug that was out of whack. Maybe the plugs are intended to point toward the secondary intake valve, where the majority of the mixture flows. I think the Primary valve is closer to the front of the head on 2 cylinders, and closer to the back of the head on the other 2 cylinders. Just a thought...
