heyy Campeck, while you got that head off why not go ahead and slap a 16 valver on there and live up to your rear emblem 
just kidding, man im really impressed by how you seem to have high spirits through all your work. I'd be pulling my hair if I ever have to do all that on my car (which I'm sure I just jinxed myself and I'll blow my HG tomorrow and snap a few belts)

Rich's headgasket is actually the odd one out in the 951 area. Most 951s burn through their headgaskets due to lean mixtures and the fire-rings remain perfectly circular. Please review my HeadgasketDissertation.pdf.
Looks like Rich's head could have used a little more torque on the studs. Make sure you use the updated torque-specs. Personally, rather than using torque-angles , I just do three passes using straight torque like the 944NA sequence. Then make the last one 75-lb•ft for a little extra clamping force. Some racers I know use 90-lb•ft. The 944GTR used something like 125-150 lb•ft with 14mm studs.
Also check to see that your block & head is flat. Low spots would reduce clamping pressure in that area.
As for Campeck's car, the coolant could've come from the head once you've lifted it off the gasket (if you didn't drain coolant beforehand). Looks like the #1 cylinder has a break in its firering? Also all the compression-rings show signs of heat and detonation. So when you do get the engine back together, find out why you're running so hot or else the next headgasket will go the same way.

here is the head
Im not shure if I torque it right? I use the angle method, but it seem to me to be more than 90 lbs! I have a breaker bar 22" and it wasn't easy...
Maybe I have not adjust the stud correctly?
