I decided to correct my timing chain stretch by installing an offset or woodruff key. The FSM on this is pretty straight forward so I just included some pics of how the woodruff key looks in place. The pics aren't as clear as I would have liked but I hope this helps someone.

Pic 1 is the old woodruff key still in place. It's just above the timing mark. Pic 2 is with the key removed. Pic 3 is a picture of the old key. I had to use vice grips to yank it out. Pic 4 is the new key and you can see how it is offset via a flange.

My timing was 4 degrees off at the crank. Now it is spot on. I swear the car is a little faster. Next job - set injection pump timing.
