Loss of about 10% horsepower.

Yep - mine was like that.  If it were a tooth off it would be out of sight below, and if the other way I suspect almost or out of sight on the top. Presuming the intake index mark is correctly aligned, being low like that would be consistent with elongation of the chain with wear.  I found the whole thing to be very frustrating.  If you want to satisfy yourself that the timing is correct, try what I did and install the ex cam 1 tooth off in both directions (no need to bolt down the retainers for this purpose) - my guess is you'll conclude that is correct as is, but is not as precise as hoped or expected. 

Ok, whether timing is correct or not, it's not likely the reason it's lost so much power as it was exactly the same way from 20,000 to 60,000 miles and was running mostly good up until this year on the same timing.

Do you have the tensioner set?  You won't be able to tell for sure until rotating it 360 degs.  If so congrats, looks much better.
