DF70 Intake Manifold Gasket

[Anubus6]

In order to remove my VST from my DF70 I needed to pull off the intake manifold. I have purchased a new gasket, but are there any other tricks I need to use during install? I notice a red type RTV on the original gasket, do I need to RTV the gasket along with the gasket?

Should n't use any sealant on intake gasket.
