Felpro makes a kit with everything to install a new manifold. But, you're new intake should have the gasket for the upper to lower, which is Trick Flow specific, also, you'll need something for the elbow to upper. (Make your own with gasket material, or a thin piece of cardboard) Search around on here for the part number, I know it's on here, that's how I found it for myself. Picked it up at advanced auto for~20 bucks. Hope that helps, good luck
