1995 Chevrolet Lumina Question: RTV SILICONES FOR SEALING INTAKE MANIFOLD OUTSIDE SIDE-WALL

Could someone recommend me a good sticky RTV silicone for sealing Chevy GM 3.1L 95, lower intake manifold outside side-wall to engine block? GE RTV IS803, Loctite RTV, or Permatex? -
Answer 1
USE DEALER GASKETS AND SILICONE -
Comment 1
Thank yoy for reply. There is no gasket needed though, this is a lower-intake sealing without removing it from the top of engine block and sealing the ridges. It is a sealing at the outside side-wall between lower intake bottom and the engine block. -

How are you going to seal it without removing it? Wiping RTV on it aint going to work! Figured you had this problem solved by now!! -
Comment 3
The current recently-applied lower intake RTV sealant is not leaking quite a lot of oil. So, I like to try seal it from outside along the side-wall, with a higher viscosity (very sticky) RTV, which can make a thick RTV wall (throwing lot of RTV at the leak!). Some RTV like GE IS803 is stated to be able to seal vertical metal surface with sufficient thickness, but I never use it. So, I am soliciting for recommendations, Thanks! -
