We only have metal ones in the truck world and ive chaged loads never have a problem really with mateing surfaces after they have been given a good clean with a scotch bright pad on a die grinder and a good check over
A truck engine is a little different, the poor old YB blocks, 200 included wobble like jelly in use, I suspect the old diesel blocks are a huge amount more rigid, so a "flexy" gasket won't be fatigue prone like a metal, I've used metal gaskets on other cars, not through choice though.
I just can't see the point of using a metal one which is more likely to have sealing issues than a composite fibrous gasket that is less likely to have issues, where the boost is easily coped with via a fibrous gasket this would be my choice.
