do these cams look normal
Its hard to tell, but pic 1 at the top looks like it might be slightly burned over the nose, but like I said, its tough to tell in the pic. Its almost like the lobe away from the gear starved for oil a little.
the ramps look ok though. But again, its tough.
The thumbnail test is better. If you cant feel or catch your thumbnail dragging it ACROSS the lobe, its probably ok because the spring pressures are so light.
If that cam was in a V8 with more than about 130 lbs of spring pressure (closed) on it...Id say its probably toast.
