Is it necessary to put sealent on the gaskets for the runners? If so which side both or just the intake manifold side? and also on the TB gasket should you have sealent on both 1 or neither sides?

 

its not really necessary to silicone the runner gaskets but if you want to its easier to silicone only one side for dissasembly later on if you intend on taking it apart. Just make sure like on everything else you use silicone on that you use the sensor safe stuff, regular silicone especially in air passage ways likes to kill O2 sensors

 

I wouldn't use silicone on them for sealant. If you want to seal them use Permatex Hi-Tack gasket sealant.
