Hurm? -n -2 is perfectly valid. It shows "all but the N first lines":
-n, --lines=[-]N
print the first N lines instead of the first 10; with the
leading `-', print all but the last N lines of each file
$ seq 1 5 | xargs -n1 | head -2

$ seq 1 5 | xargs -n1 | head -n 2

$ seq 1 5 | xargs -n1 | head -n -2
