9333s have metal rings in them. they are a good gasket i have them, i used them with my blower pushing 13 psi and i never blew a gasket, your tune is going to affect the HG life rather than the gasket itself.
i think there is a myth that boost kills gaskets quicker, IMO what kills them is raising boost without adding fuel or retarding timing. since a blower/turbo raises compression, you become MUCH closer to the detonation threshold, and without retarding timing or adding fuel to control combustion temps, your going to detonate and most likely toast the gasket. its detonation that kills gaskets not boost really. make sure you tune the car or have it tuned good and you will be fine.
people seem to up the boost and blow a headgasket and blame it on the boost pressure, but usually its the lack of adding fuel or taking away timing
i ran 1011-1s for like 30 mins when i had irons heads, but i had the heads off for some other issues so i just went with what everyone said, the 9333s, and i havent had any problems.
plus i think the 1011s are a little thinner gasket which will slightly raise compression which isnt really the ideal thing to do with a blown setup.
