I believe that without a mark on the front of the cams, you should start out with both Woodruff key slots facing up.

And, it sounds as though you did the timing correct to me. I just completed essentially the same procedure on my 993 3.6, which I back dated to the old adjustable cam gear timing used on earlier designs. So, neither of my cams had any markings on the face. So, my static setting was TDC on #1 coinciding with both cams set with the key slots facing up. One of the keys to having done it correctly, is that the timing needs to be as close to the same on both sides of the motor. For instance, if you were able to hit the timing so that you were, in fact, at 1.26 mm at TDC on #1, you should move on to timing the #4 intake, and attempt to duplicate the 1.26 mm on that side of the engine (at TDC for #4). Putting it another way, hitting the 1.26 mm at TDC is secondary to making certain that #1 and #4 intakes are open the same amount at TDC.

Proof is that the car is now running fine!

I think you nailed it!
