Make logo as big as I can, but reduce the Header size?

[thegreywizard]

So I have the logo set as big as can, to 300px

But this also increased the size of my Header quite a bit

So how can I reduce my header size, but still keep my logo at the maximum 300px size?

swankycrystals.com 

Is the website. 

I'm using Refresh for my template

Thanks!
