Intake manifold gasket installation help

So, getting ready to fit the manifold and just have one more question. The tabs that fit into the cork gaskets in the corners (pictured), that are part of the head gasket; do these tabs get bent down to hold the gasket before the manifold is set down, or does the manifold itself push them into place as its bolted down? I know RTV needs to be in these corners, and the water ports, but am wondering if the tabs need to be pressed down as well.
