Oil in Water - Need Intake Gasket Recommendation

I hope I'm wrong too but it just happened to another member. It's a very common problem. If you disagree, then explain how water will move horizontally four inches and go into the intake port. That thread should still be pretty close to the top. You could see the head gasket pushed out looking through the valve cover area. Coolant leaks out and is sucked right into the intake port. Like I said, I hope I'm wrong. I'd sure be lookin at it though.

I appreciate the input. You can clearly see in the photo that the gasket did not distort or push out. Water was also leaking into the intake runner on cylinder #1. So the two cylinders closesed to the water jackets were affected. I believe the gasket has deteriorated. Like I said, I built this engine 20 years ago, so maybe there is no problem and it's served it's purpose.
