The "port_in_redirect" directive only alters behaviour of nginx 
itself (for trailing slash redirects, rewrites and so on), and 
it's expected that it does nothing for redirects returned by php.

With "fastcgi_param SERVER_PORT 80;" php should be fine, and I 
suspect that problem you see is actually related to your browser 
(or varnish) cache sitting here from previous configurations.  

If clearing cache doesn't help, please provide debug log (see 
http://wiki.nginx.org/Debugging), it will show what goes on here.
