hey everyone i have a d16y1 turbo setup

i was hoping i could get some info please first of all what is a better than a oem 3 layer copper coated head gasket... i've been told that a stainless steel gasket should do the job,,,,,if any one can help where i can find this gasket???? and if anyone knows anything about them ( by the way i blew the head on the dyno 121.4kw at 5.5 pound )...not much for a fully worked motor...

much appreciated for knowledge...
