I had this problem when I first filled my system after a rebuild. 2 or
3 bleeds over a few weeks gave me a progressively firmer pedal. Later,
a list-poster said that little air bubbles tend to form inside calipers
and other dry parts- I think a few firm-but-gentle whacks with a hammer
were suggested!

The original washers were thick and cupped, and had an oversize hole, so
that they can rock back and forth to spread force between the
manifolds. I don't know if they could handle 1/16", tho... I had the
same problem with an aftermarket header that was too thick, so I had a
machine shop surface it down to the same thickness as the intake. THey
have these big belt sanders, see...
