Jba Shorties install requirements

Hey guys, new member on the site and want to know your insight on whats required before install of these shorty headers i.e. new manifold gaskets, header bolts, etc.. and also where to attain them
Or even some general tips
Thanks guys and much appreciated
By any chance do you have the gaskets on the site? I bought the headers from a member on here but never came with the gaskets. They did already come with with cats welded on so that was a plus
