I've never used silicone and I've never had a leak. Just make sure the new gaskets have those little tabs that hold them to the runners. If not you can remove them from your old gaskets and put them on the new ones. They really help during assembly.

Do not use any silicone/sealant. If you ever have to remove the plenum/runners, you will cuss uncontrollably.
