Cam lobe discoloration normal?

Hey guys, finally got started on my slow coolant leak from my intake, got the intake off, got everything cleaned up for the most part. Still a little oil and coolant i have to get out of the valley, I just had a question about the discoloration on the cam lobes, does it look normal?








also hows the wear look on the rocker arm rollers?






Gonna try to button up the intake tomorrow before the cold weather moves in
