To my knowledge, the ONE thing that gmail checks is the Message-ID: 
header, if that matches, it is a duplicate and dropped. It is not 
checking for the messages being "identical", it is detecting 
"duplicates", as defined by the RFCs for Email (if two messages are 
different, they must have different Message-ID:s).
