The ability to replace the heads would give us all LOTS of options! GT3 heads with higher compression and more aggressive factory cams??; Turbo heads with lower compression, then add turbos or a supercharger?? Just get another good set of 3.2 heads and give them a good porting/polishing??
Since you're in it up to your elbows, I'd love to hear your thoughts.
Of course, if the bottom end is toast, all of this is out the window!
Best wishes getting your baby running again.

Hey J,
I haven't located the exact location of the failure yet. Time is an expensive commodity in my day-to-day, but I am getting closer. Both heads are removed, and it appears that the breach is located within the crankcase. It is true that the 986 case is really a 996 3.2 for the 2000 S, but I haven't looked into if the GT3 or 996 turbo head geometry would work out. It's also hard to say if the current firmware would have to be tweaked to take advantage of these changes. In the long-run it would probably be cheapest and the most reliable route to just replace the power plant with a new 3.4 or 3.6.
Thanks for the good wishes, and stay tuned...
