I realize my question may be irrelevant…
I actually achieved what I wanted by editting the css padding and margin of the header.
/* Change header height */
.site-header-main {
padding-top: 0px;
padding-right: 0px;
padding-bottom: 0px;
padding-left: 0px;
}
.no-site-tagline .site-title {
margin-bottom: 0px;
}
ul {
margin: 0 0 0 0;
}
