The failure is a design/material flaw.
The material itself doesn't stand up well to the coolant, and then it'* being held in place by a plastic carrier, itself only doweled in two locations across the length of the head. Mix the combination of gasket material, plastic carrier, coolant, and lots of heat, and it'* a winning (read: losing) combination.
Metal carriers help keep the gaskets from deforming, and the newer gasket materials are designed to withstand the coolant/temperatures for longer periods of time. Put both of those upgrades together, and you're looking at a much longer life for your gaskets...
