Except 993 Turbo head studs (dilavar) seem to work really really well. Many of the high output 3.6 to 4.0+ liter race engine builders exclusive use the 993 Turbo head studs. I am not saying the SuperTec studs aren't great, but it seems odd to put all dilavar heads studs in the same bucket when the 993 Turbo parts work great.
