Jeff,
The pictures don't show much detail, but things appear to be typical. I inspect at the cylinder wall, valve seats, and head to block mating surfaces for scratches, nicks, voids, gouges, any imperfections. The exhaust valve seat may show signs of moderate to severe erosion on engines with a lot of hours.
Clean off as much of the carbon with a wire brush or wheel, be careful with the aluminum head. The gasket area on the aluminum head should be resurfaced. Start with 320 grit wet sand paper on a very flat surface (plate glass), move the head in a figure 8 motion on top of the wet sand paper until the gasket area is perfect (no scratches). Finish up with 600 grit or higher. If you are not familiar with this, ask for more info, as I did not get too detailed.
Jim
