Bogofilter recognizes the header lines and adds prefixes to all header
tokens before scoring the message.  Most header tokens get a "head:"
prefix, but tokens in the "To:", "From:", "Return-Path:, and
"Subject:" lines get special tokens.  Adding header lines will
add more tokens to use in scoring, which will help.  The open
question, though, is whether adding 1 or 2 (or even 5) tokens
will make a noticeable difference.

HTH,
