Intake manifold gasket installation help

Man I wouldn't sweat it. It's over and done. They'll seal a good while before anything happens. Heck, you might have even sold the car by then. My only point was that RTV will not break down and leak. Period. It's just a very permanent fix. Millions of engines used cork for decades and it works. I agree with @cudamark 100%. Blow some extra coats of paint on the cork end gaskets and call it done. That'll seal them and make them last even longer. That's a good idea.
