Ruben ,
We use the Seattle shop of MSHS. The quality is above what I was getting from Wartsila, they do send the report both to me via email and also shipped with the head.
Turn around time is about 2 weeks but they can do it faster if I wanted to pay the fee to expedite the process. The shop foreman has been down twice to make sure we were happy with the process. I would highly recommend them.
