There was RTV on the four corners where my LIM gasket met the intake seals. RTV on the head gaskets will just burn off from the heat. Unless it'* high temp.. refer to the back of the tube, to see it'* maximum heat tolerance. What temps do the heads see? I'm going to check mine shortly. I suggest putting a small amount on the LIM gaskets and intake seals. Put a little more on the intake seals, that is a common leak spot.. or at least on my engine it sure as hell was. I can post some pics of my intake, with gaskets that leaked, before cleaning. Trust me, it'* not pretty.
