Yea just seal it. After the pre cat you will need some decently thick metal & make a template from the tubes. There is one or two bolt holes on the flange. And then on the breather take out the valves the tubes hooked to & seal that off good. Some thin metal, RTV, and a few rivets. Will try to get pics of the breather later. I left the exhaust mani & precat about 80 miles from here. lol and never thought to take a pic of that
