How to Increase Header Height of Blogger Blog?

[Brady Partridge]

I've installed a custom banner on my blog but haven't been able to increase the header height to accommodate it. No matter what changes I make to the code the header height refuses to budge. (I posted my predicament on the Blogger support forum several days ago, but if anyone has a fix, he's keeping it to himself, lol.)

This is what the header looks like without the custom banner.

This is my blog with the custom banner.

As you can see, the banner overlaps the bottom of the header. I know I could shrink the banner so it would fit snugly in the header but it doesn't look nearly as good.

Here is the header code.

#header-wrapper {
    height: 158px;
 margin: 0 auto;
    text-shadow: 1px 1px 0 #000000;
}
#header-inner {
    margin-left: auto;
    margin-right: auto;
padding-bottom:0px
}
#header {
top: 7px;
position: relative;
    color: #FFFFFF;
    text-align: left;
}
#header h1 {
    font: 293% family,Lobster,Serif;
    letter-spacing: -1px;
    margin: 0;
    padding: 42px 51px 1px 81px;
    text-transform: none;
}
#header a {
    color: #FFFFFF;
    text-decoration: none;
}
#header a:hover {
    color: #FFFFFF;
}
#header .description {
    font: 100%/12px 'Shadows Into Light',Trebuchet,Arial,Verdana,Sans-serif;
    letter-spacing: 0;
    margin: -7px 0 0;
    padding: 0 14px 0 81px;
    text-transform: none;
}
#header img {
    margin-left: auto;
    margin-right: auto;
display: none;
}

Many thanks for your help!
