Using Multiple Custom Fields in IF Statements

I was wondering if anyone knew a clean way to use multiple custom fields in an IF statement.

At the moment I have it spaced out, so each custom field “SponsorHeading#” has it’s own if/else statement:

if(get_post_meta($post_id, 'SponsorHeading1', true)) {
       echo '<h2>Summit Sponsors </h2>';
       			}
       			else {
	       			echo '';
       			}
       			if(get_post_meta($post_id, 'SponsorHeading2', true)) {
       			echo '<h2>Summit Sponsors </h2>';
       			}
       			else {
	       			echo '';
       			} 

and so on for 3 more custom fields. I'd like to have something cleaner like:

if(get_post_meta($post_id, 'SponsorHeading2', true)) || if(get_post_meta($post_id, 'SponsorHeading2', true)) || if(get_post_meta($post_id, 'SponsorHeading2', true)) {
      echo '<h2>Summit Sponsors </h2>';
}
     else {
            echo '';
}

or something along those lines to clean it up but nothing I’ve tried has worked.

Any suggestions?
