I believe your header() commands only REPLACE any headers PHP would
have sent, but any other headers it's gonna send, it's still gonna
send them.

I think that will suppress headers... by issuing an ERROR that a
required argument is missing :-)

No.
That is not a valid header, for starters.
You MIGHT be able to "wipe out" the headers PHP sends by doing
something like:
header("Content-type:"); //Wipe out Content-type:
but I wouldn't cound on it.
Sounds to me like the remote server isn't actually using HTTP at all.
HTTP without headers is just not HTTP.
You may want to write your own "server" in PHP using sockets -- but
then you'll need to convince the remote server to connect/use that
different "server" you have written. Either connecting on a different
port, or to a different domain, or a different URL (maybe) so you can
configure your box to use your "server" for these weird requests.
