Share your Pro Comp head knowledge

From what I have been reading, Pro Comp heads have a good casting but need a cleanup of the ports and some in the bowl area. I am thinking about buying a bare set of Pro Comps and would like to know what I need to do, cleanup wise, to make sure they perform the way they should. Then I will have quality parts installed. If anyone here is knowledgeable about these heads, please share what you know for those of us that have to do it ourselves so we can spend that little bit of money we can save and put it elsewhere in out projects. A step by step would be awesome. Maybe even make it a sticky in one of the forums. Thanks in advance for anyone's help.
