Machform already use h2 tag for the form title, may be you refer to h1 tag on the logo. If so, you can change the tag from "includes/view-functions.php" file. Edit the file and go to around line 1847 for this code :
<h1><a>{$form->name}</a></h1>
then change it to
<h3><a>{$form->name}</a></h3>
After that, edit your form css and search for these code :
/**** Logo Section *****/
#main_body h1
{
background-color:#dedede;
margin:0;
min-height:0;
padding:0;
text-decoration:none;
text-indent:-8000px;
background-image: url('../../../images/machform.gif');
background-repeat: no-repeat;
}
then change it to
/**** Logo Section *****/
#main_body h3
{
background-color:#dedede;
margin:0;
min-height:60px;
padding:0;
text-decoration:none;
text-indent:-8000px;
background-image: url('../../../images/machform.gif');
background-repeat: no-repeat;
}
that would do it
