That document made 80 the official port for HTTP (www). However there is nothing about port 443 in that document.
It is not clear why port 443 was chosen. However, the previous RFC document had a gap from 374 through 512, but in RFC1700 the space from 375 to 451 was filled. It is most likely that the numbers were simply given in order of request.

Port numbers are sometimes seen in web or other uniform resource locators (URLs). By default, HTTP uses port 80 and HTTPS uses port 443, but a URL like http://www.example.com:8080/path/ specifies that the web browser connects instead to port 8080 of the HTTP server.
The answer is 80 and 443 by default.
