340 oil pan gasket

I need a tip on what type of sealer to use on the rubber seals and the cork gasket that I just bought from mopar. I used Permatex #2 gasket sealant on my 440 block to keep the gasket inplace. The 340 with the rubber flap seals at the ends of the pan not sure if I use Permatex Hi-Temp Silicone let the silicone skin up for an hour then install pan or no silicone at all.

This is my first build on a small block and trying to keep away from the notorious oil leak. Any advise

THANKS CHRIS
