Location of a particular CSS entry Options

[RSJai]

I'm trying to use a wordpress theme on my website Randomstumbles.com, and having issues with the logo getting clipped out.
Inspected the logo using both firebug and Chrome Inspect element and see that the logo box has a size of 70px set.
If I change that to 80, the issue gets resolved.
I've been trying to locate that one value, but have failed.
Have very basic understanding of CSS, but tried to inspect the style.css file.
There was this entry for logo
#header h1, #header h2 {
text-indent: -999em;
min-width:286px; }
#header h1 a, #header h2 a {
background: url(images/logo.png) no-repeat;
min-width: 188px;
display: block;
min-height: 70px;
line-height: 70px; }

Changed both of the last values to 80px, but nogo.
Tried looking at the entire style sheet and some functions in the theme, but could not pinpoint where the 70px was mentioned.
if you inspect the logo element, you can see that the value is not getting pulled from the main style.CSS file, but rather from index:(25)
Can someone please help me in identifying the location of this value?

Changing min-height to 80px works for me.

Thanks Pandy!
My issue is, changing that to 80 in style.css does not make any difference.
This value is getting pulled from somewhere else. Look at the location of the css style, the values in style.css are getting overwritten by values from index:(25)

Index:(25) refers to an embedded style block in your index page. You have to change it there too. Or if you already have it in style.css, just remove it from the style block.
