Intake manifold question

[GMC Guy]

i'm taking my edelbrock manifold off to clean it really good and to replace the old gaskets. i have a new set of fel-pro gaskets already, but i just need to know where to put RTV and basically the best way to put it back together so it won't leak. i heard that using RTV instead of the rubber end seals works better and lasts longer. i know it's not rocket science, but i'd just like to know the correct procedure to remove/replace the intake, so i don't have any leaks. thanks.
