Yes I'm sure. From the link Thomas sent,
Any property specification, unless it is postfixed with a `+`, will *reset*
the value of that property to its current value.
C-c C-v <TAB> (for me, Charles uses C-c C-v C-i) withitn a code block shows
you the header args that are set for that block. Useful for debugging.
-k.
