Reply To: Increase height of header image and center it

You can add a height to the #header section of your css….or even the #header title area around line 685 –

.header-image #title, 
.header-image #title a, 
.header-image #title-area {
    display: block;
    float: left;
    min-height: 120px;
    overflow: hidden;
    text-indent: -9999px;
    width: 50%;
}

Notice its currently set at min-height: 120px
