How to request HTTPS using http.request

In the docs I can see there is provision for HTTPS when using http.get, you just pass a https:// url and it works it out. But what about when using http.request?

  var options = {
    host: 'google.com',
    port: 80,
    path: '/',
    method: 'GET',
  };

  console.log('about to http request');
  http.request(options, function(res) {
    console.log('request cb');
    res.on('data', function(data) {
      console.log("HTTP> "+data);
    });

    res.on('close', function(data) {
      console.log(data);
      console.log("Connection closed");
    });

    res.on('error', function(err) {
      console.log(err);
    });
  }).end();

Works fine, but if I change the port to 443 it just stalls. I assume because its trying to talk HTTP to a HTTPS port. I don't really want to use tls.connect because that gives me a socket rather than a https connection.
