I understand you want all the valve heads the same height in the chamber so with sunk seats, you're replacing the seats and getting all the heads to sit at the same height...got it. But in the picture where you say you have .060, you're measuring from the deck height and what? I can't see but I'm assuming you're going to the top of the seat you installed?

Once all valves are sitting in the same place in the chamber, the cc's should be closer to start with...am I on the same page or in left field?

60 is the degree cut in the seat, that didn't exist before. This is a good part of the low and mid flow pick up.
