Guess your cylinder head was fit for purpose then
The elastomer gasket is great. As we all know, time/temperature/chemicals is what that deteriorate the elastomer seal and make it fail at some point, making the water to go either out or into the oil. If a failing elastomer gasket is identified and replaced at an early stage there will be no problem to just replace it with a new one
In my case, the car has been driven with a failed gasket until the car was not driveable. As mentioned earlier, this car was identified with a failing HG for 2 years/1000miles ago. The owner did just ignore this and continued to use it, wrecking the cylinder head.
