Beefier ... could he be any more ambiguous ?

In order to even contemplate whether or not a STI multilayer gasket would solve known headgasket issues, one would need to know the actual cause of the failures ... as far as I've read ... there is a lot of speculation but little in the way of actual evidence.

The idea behind a semi closed deck is to stop the cylinder that the piston rides in from "walking" or moving sideways due to the extreme pressures crated under boost [turbo] situations. If the problem is the head bolts backing out or flexing or bad cooling flow design ... I'd think that it would fail eventually regardless.
