I don't even use the cork gaskets anymore. If you remove the little pin that holds them in place, which you usually have to do with an aftermarket intake to keep the pin from keeping the intake from sitting all the way down, the cork will slide out of position when you torque the manifold down. The gap is usually pretty small there using aftermarket intakes, so I just run a few beads of RTV at the front and rear of the manifold. Works better.
