While you have the intake manifold off you may want to change the heater hose quick disconnect with a steel one (the factory ones are pot metal and will start to leak sooner or later). If you have the manifold off and the quick disconnect breaks while taking it off it's better now than later.
If you already have a steel one no change is necessary.
Here's a tutorial:

The steel fitting should be available at your local auto parts store and here is what it looks like:

The fitting is $6 and the FelPro MS98000 T intake gasket is $55 at rockauto.com (if you look on the internet sometimes you can find a 5% off discount code that you can apply to your order).
Good luck
