Some more information on this, the cached tinyMCE gz file is stored in

wp-content\uploads\js_cache

Delete this file.

The newly generated file will pick up the changes mentioned in my previous post.

You need to edit this file

wp-includes\js\tinymce\themes\advanced\editor_template.js

Search for

theme_advanced_blockformats:"p,address,pre,h1,h2,h3,h4,h5,h6"

Edit this code directly for your desired options. You’ll need to do some cache clearing before you see this come through in the editor, but it *will* work.
