Ernie may be on to something. Many of you with the Big inch Fe's rightly use aftermarket heads made of aluminum. They will by nature move around a little because of aluminums expansion properties. That being said, it's possible that after several heat cycles, the clamping load is diminished, allowing the gasket to be forced towards the intake port by the pressure exerterted on the gasket by the pressurized coolant.
