I have an assortment of carbide cutters that I like to use but I find that this one works particularly well around the valve guides:

Although most of the fine cut burrs are recommended for ferrous metals, I find they work well on aluminum because they produce a better finish.

 

thanks, is that for a dremel? 6" right?
