Valve seat cutter and proper pilot

[Bored&Stroked]

What are you guys seeing as far as the quality of the seat finish and concentricity? Anybody use a seat mic afterwards to see if there is any run-out?

I'm used to stones where you have a really nice concentric and almost polished seat. I'd love to see some close-up pictures if any of you have them. I might be able to use my Kwik-Way Seat cutting setup with one of these Neway cutters to do the seat work (depending on the quality of the finish and concentricity).
