    I have a couple of questions about intalling an intake manifold on a 350.
    I didn't use that rubber gaskets on the front or back on the engine-my eldebrock maunal that came with my manifold says not to use them. I put some silicone gasket stuff.
    Will this work no problem? I also realized after I put the manifold on that the silicone is non hardening. I am thinking now that I should have used some stuff that hardens. What do you guys think??
    If I have to put some different silicone on can I re-use the intake gaskets I put on??
    Thanks for the help.

    What type of RTV did you use? It sounds like you used an anaerobic sealer. I would use -The Right Stuff made by permasex, or the RTV GM parts departments carry- used to be GMS. Also the Mopar RTV is great too. I personally wouldn't re-use the intake gaskets.

    Sounds like permatex non hardening gasket maker. I used black "gorilla snot" (non hardening) on the head and intake surfaces but on the ends where the rubber gaskets go I used RTV grey in their place. The Right Stuff is supposed to be really good too.
