Hi,
the 3,6 automatic transmission will probably not last for too long when you add another 60Nm as produced by the ABH to its load. So it would be a good moment to switch to a manual gearbox, as you've planned it anyway, as far as I understood you in the first postings. It would also help on avoiding problems with the wiring harness, as the PT and the ABH (or better said: Pre-Facelift and Post-Facelift, but each ABH ist Post-Facelift) have different wirings (at least at some points).
In general, I haven't _read_ about any cracks in a V8 head the last 8 years, but that doesn't mean it couldn't happen. Regarding the instructions on how to remove everything, I've sent you an email a couple of days ago. I'll PM you again.
Regards
Bastian
