Intake gasket Help

The metal and cork is what the factory used. It works fine when everything is clean as new. If the heads and intake surfaces are clean and flat, no problem.
Oil will migrate through the cork very slowly. The cork blows out if the pcv system gets clogged. Silicone will blow out too if conditions are right but at least it doesn't get saturated and look bad. :)
I use the Felpro print-a-seal gaskets and silicone when working under the hood. On a motor stand I would use the steel mainly because they are in the rebuild kit :)
