chas,
You are not alone....
The Fel-Pro (fail-prone) gasket droop fiasco has been going on for years. Mostly in street engines that have a lot of heat-cool cycles. Race engines that are torn down often don't have the problem.
Have a look here

and also follow the links that are in that thread. Fel-Pro has finally admitted they had a problem and now supply this gasket with a steel shim reinforcement.
What compensation do they offer? HAHAHAHAHAHAHAHAHAHAHA
Welcome to the club. Sigh,
Tom
