Perfectly normal.  The stock lifters are effectively cups, they have no
drain holes for the oil to run out of the hole where the pushrod end rests,
so the oil just lays there and tends to form sludge.  In fact, it can be
tricky to extract the pushrods without pulling the lifters up out of their
bores.
