Need some CSS help with Responsive child theme

Latest version of Responsive and WP installed..

I’ve been trying to get a particular layout using only CSS for the H1 .entry-title .post-title class in my child theme for Responsive

In order to reproduce the mock-up I am working from, I need a left floated image, 600x137px followed by the right floated page/post H1 title that winds up being vertically & horizontally centered in the remaining 370x137px space.

Then on top of that, the mock up has a gradient behind the title text… but I’ll worry about that later.

I’ve gotten some parts of it to work with CSS alone and not hacking theme files. but I can’t get the H1 to hover where it needs to go.

Hopefully the above makes sense, and even more so, hopefully some kind CSS guru could give me a clue..

Here’s the underlying HTML generated by Responsive

<div id="content-full" class="grid col-940">
    <div id="post-8" class="post-8 page type-page status-publish hentry">
        <h1 class="entry-title post-title">

	PAGE POST TITLE

        </h1>
        <div class="post-entry">......

Here’s what I’m attempting to make work…

/* this part works, header.jpg is 600px wide and is right where it needs to be */
.post-title , .entry-title {
padding:0px; height:137px; width:100%; vertical-align:middle; border: 10px solid #606060;
    background-image: url('header.jpg');
    background-position: left center;
    background-repeat: no-repeat;
}

/*
this part doesn't seem to work at all.. I even left some of my desperate attempts in like (align-self, and disabling text-rendering)
*/

h1 {
align-self:center;
font-size: 22px;
line-height: 137px;
vertical-align: middle; /* looks like it is set to top.. can't find why */
padding-right:32px; /* attempting the appearence of centering.. no joy */
width: 353px;
height:137px;
background-image: url('back_header.jpg'); /* image isn't displayed.. likely covered by the above image */
background-position: right center;
background-repeat: no-repeat;
text-rendering: none;

}

Again, I’d really appreciate any suggestions.. been battling this challenge for way to long
