Re: 12 Point Bolts....
Yeah, johnnyb you have to clear this issue up. I would personally be very surprised if a car manufacturer, especially a German one, used Torx bolts to secure an engine head. I agree with crankin500, and like I said before, you need a quality Torx bit for this kind of thing. On my Jeep Torx are used extensively, but only for interior and exterior fastening, nothing much in the engine compartment (although the Jeep 4.0 inline six has been replaced with a 5.7L Chevy LT-1 in my jeep.) Torx are not really ideal for high-torque applications as the bits don't stand up to it. It would make more sense if they're simply 12-point bolts, not Torx; is it possible that you're confusing these? Torx sizes are designated by a T and then a number, like T-6, T-8, T-12, T-20, etc, the smaller number being the larger size.....obviously a 12-point bolt is sized like any regular socket, 1/2 inch, 9/16, 10mm, 12mm.
You should post pictures of this.
