Blown head gasket? Help!

[8litercobra]

Once upon a time, I had a windsor wound out, sudden engine seize, mucho smoke from both pipes. I figured the motor was toast. Towed home. Poked around a bit, out with the plugs, most cylinders had liquid in them, as did the oil pan. Everything I checked was fine, great compression everywhere. started to open up the top. Noted very little torque on all intake manifold bolts, lifted up the intake. Over the #4 cylinder, there is a coolant passage adjacent to the #4 intake passage. The 1/2" piece intake gasket had failed at that point, and allowed coolant into #4, which blew it back into the intake and all the other cylinders. After oiling all cylinders and cranking with the plugs out, I just reassembled plugs, pan, and intake. No damage whatsoever, thank my lucky stars! Kept that car about 10 years before selling it. No problems, but I checked intake manifold torque every day for a week, every month for a year, the semi-annually after that.
