You've lost me with all the headers and headings in your text.

The cache validation logic is supposed to be clever enough to detect 
when the dependencies of a page have altered since the cache was created 
and so invalidate the cache version.  I don't recall whether or not 
first headings changes (effectively metadata changes for the dependent 
page) do in fact invalidate the cache.  Off the top of my head they 
should (when  use_first_heading is in effect), assuming the resources 
required aren't excessive.
If its not happening you may want to raise a bug/feature request.
