Default ports blocked outbound - standardized?

I'm auditing the list of ports blocked outbound on my 'inside -> out' access-list; is there a standardized list anywhere of dangerous port numbers that should be blocked outbound by default in a MS Active Directory domain network?

I wanted to compare my blocked port list for deficiencies.
