Just get a bufty and dont clean it - just like mine

Does/would this actually happen? I’m not quite sure why running a more powerful engine would overstress the radiator/cooling system header tank? Has it ever happened to anyone?
Would someone like to explain?
Didn’t Martin Hadland run a normal plastic header tank in his Escort?
