There is simplyer solution:
you can add this line to your theme files
<{if $block.title|truncate:9:"" == "no-header"}>
and each block name that will start with "no-header" won't have a title
my blocks at the theme files looks like this ( you can do it to all your blocks locations - right, center, left and so ... )
<{if $block.title|truncate:9:"" == "no-header"}>
<div class="blockTitle"><{$block.title}>div>
<{elseif $block.title != ""}>
<div class="blockTitle"><{$block.title}>div><{/if}>
<div style="padding-bottom: 5px;" class="blockContent"><{$block.content}>div>
