Better than proposal 180 is pt-spec.txt, which is more up to date.
https://gitweb.torproject.org/torspec.git/blob/HEAD:/pt-spec.txt

For the extended OR port on the server side, see
https://gitweb.torproject.org/torspec.git/blob/HEAD:/proposals/196-transport-control-ports.txt
https://gitweb.torproject.org/torspec.git/blob/HEAD:/proposals/217-ext-orport-auth.txt
(But ignore the TransportControlPort part of proposal 196, as that's not
implemented.) For the extended OR port, you may also want to look at
some existing source code:
https://gitweb.torproject.org/pluggable-transports/obfsproxy.git/blob/b88efc0ce3f145d5e767d5b938889e99b47021b7:/obfsproxy/network/extended_orport.py
https://gitweb.torproject.org/pluggable-transports/goptlib.git/blob/abeea884f554b4119ebd84974c612c0dca6ce941:/pt.go#l581
