I had mine done at ASF Machine, and would recommend them to anyone. Joe is great to work with and really did a beautiful job, I regret not taking pics when I got the heads back from him.
Here is one of the heads after a quick tear down after a few hours of run time. Not shiny new, but I did give em a quick cleaning
