The contact surface side doesn't look too bad. The main things you have to worry about is warpage and heat damage marks. The heat damage marks look like metal that is heated that turns a blueish purpleish color. My last clutch was fried and they had to replace the flywheel because the wheel was warped around those marks because of the intense heat.

The flywheel in the pics looks like it could be refinished and reinstalled with no problems at all.
