Pulled the camshaft gear and found that I had not put in an offset woodruff key before.
So, I am only at 6 degrees stretch and the FSM allows for 10 degrees.
The gears look good from what I can see.

I have decided I am just going to put in a 3 degree woodruff key and not mess with
rolling in a new chain, finding the right crimp tool and changing out gears.

Also, it's confusing to order the right key.
Camshaft woodruff key degree is 1/2 of the reading at the crank.
You can get them in 2,3,4 or 5 degrees.
Attached is a pic I took from my 617 FSM which includes the part numbers.
