Agreed. H tags can be triggers for special treatment, such as page breaks. Check your XPath expressions on the Structure Detection tab of the conversion dialogue.

I generally use: Insert page breaks before: //*[name()='h1' or name()='h2'] to ensure that I do get breaks on every H1 and H2.

Alternatively you may be able to use something like:

<h1 id="sigil_toc_id_1" title="Title Page">Berger's 7mm VLD Bullets
<br/>&nbsp;
<br/>Part 1: Properties and Test Results
<br/>&nbsp;
<br/>Bryan Litz</h1>

but this feels a bit clunky.

So I would go with:

<h1 id="sigil_toc_id_1" title="Title Page">Berger's 7mm VLD Bullets</h1>
<p class="hdr1">Part 1: Properties and Test Results</p>
<p class="hdr1">Bryan Litz</p>

where .hdr1 is something like:

.hdr1 { font-size:2em; margin-top:0.5em; margin-bottom:0.5em }

or whatever sizes you need to match your h1 tags.
