What the fuck do you know?? So, it's not normal for a head gasket to fail at 2-bar on a 350bhp CVH?? You are a perfect example of the toilet of RST owners and the reason why anyone in their right mind wouldn't map a car for you because ANY failure and you would blame the mapper.

Whether the head failed due to a weakness in the head or the gasket failed is irrelevant. For you to blame the map is just a total guess. Poor mapping would have resulted in Det, you have the pics above, show me the Det, or is it as I suspect that you don't even know what Det looks like??
