There is a minimum height set by default in the css on line 2043 –

.header-image .site-title a {
    float: left;
    min-height: 164px;
    width: 100%;
}

I would change your height to 82px since that’s the size of your image –

.header-image .site-title a {
    float: left;
    min-height: 164px;
    width: 100%;
}
