I'll be getting my plenum kit from Hughes soon. I was wondering, I am going to install a new intake manifold gasket. Do I need to use RTV silicone anywhere on the gasket or is it a complete seal? This is my first time doing it, I have no knowledge of this what so ever. Thanks.

 

You need RTV only in the corners where the four gaskets that frame the intake manifold on the engine block meet.
