In order for a better gasket to "fix" the problem, it would have to be the gasket's fault in the first place.
An MLS gasket will end the problem of dissimilar metal expansion rate with respect to the iron block/aluminum head situation. MLS gaskets are also nearly immune from electrolysis so that problem is essentially eliminated as well.
The fact that all modern engines use MLS headgaskets, and a large percentage of them are turbocharged or supercharged lends credence to the above statements.
But increased boost, lousy fuel, clogged cats, ageing cooling systems, low coolant level in general, ageing/failing fuel pumps, partially clogged injectors, or any other number of supporting system failures common in these cars will blow even the best headgaskets. It doesn't help that Ford saw fit to set these cars up with an excessively aggressive tune that relies very heavily on a marginally functional knock sensor.
But having said all that, properly installed 98+ MLS headgaskets can be considered a permanent solution. Yes.
