Gasket sealer recommendations for Intake, pan, and timing chain cover (360)

OK there are 2 different sets of intake manifold gasgets in the felpro gasget set. one set is steel and the other set is blue composite, I'm assuming I should use the blue gasgets and also assume that I don't need to use a gasget sealer with the blue gasgets with the exception of the corners. Please correct me if I'm wrong. Don't know what I'd do without the advice I get from all of you guys. It's MUCH appreciated.
Yes the blue ones and yes to rtv in the corners. Some guys say they use sealer around the water ports but I have never in 35 yrs of using them and never had a water leak. I also use high temp pipe sealer on the bolts to prevent any water or oil wicking through the threads. You can get that at NAPA and maybe other parts outlets
