all machines need udp opened to get response from ntp and dns.

moving these to tcp would actually seriously help with filtering ddos, but good luck.

Yeah but as I understand it, Port 22 doesn't just sit open on a machine waiting for any connection.

Running a quick netstat -p udp doesn't show any UDP entrys with LISTENING status.
