Intake Manifold side gasket installation question

[AZ59apacheguy]

Hi. I have a question about applying the side gaskets. I'm using Edelbrock Gasgacinch and according the the video, it says to apply Gasgacinch to the coolant ports of both the Heads and gasket. Why not apply Gasgacinch to the Intake Ports of the Head and gasket as well? Doesn't using a sealer on the intake ports give it the best chance to seal? I'm using the Fel-Pro MS9617 Blue gasket kit. Also, should the dabs of RTV you put in the corners go underneath the very tips of the ends of the side gaskets? Thanks for your time
