Just to help explain the pictures
Basically the first lobe on the intake cam (the lobe closes to the core support) has simply squared itself off and instead of having a smooth radius, now makes almost a block shape.
The lobe also has damage and scoring. Pretty much useless unfortunately
Charles, another thing I just thought about: Valves. The the cam lobe took such a beating, it's makes me wonder if the valves did as well. Probably not, but something to think about if a new cam doesn't fix the issue.
I also have a set of stock cams if you would like to try out to see if the noise goes away.
