Is it possible your bars are contacting in a similar way?
Hi Mrekim,
Your WD bar and cam wear is "normal" for the DC. They have a forged WD bar on an all cast cam arm. The wear is hitting on the high spots since the 2 are not a machined precision fit.
If you mark the left and right WD bar and always use it on the same side all the time, after tweaking the DC into perfection, the cam and WD bar wear into a perfect matched set. If you keep flip flopping the WD bar, that wear pattern starts all over again, and again and a again.
See here my cams and older WD bars this is 25K miles and with a 1,200# TW.



I'm still using the same cams, just different WD bars on a 1,600# TW and the wear is not a lot more after another 30K miles.
And if I ever wear them down a good 1/4" or more, well flip them over (left on right side and right side on left) and wear again. In my case I do vase-o-line the cams with this heavy TW. It cuts the noise and the wear down. Since my TW is so much, the little loss of friction is not noticed on my setup. Just do not use grease, it can cut too much friction.
I expect I can easily get 100K miles before I even think about flipping the cams over and wearing again.
Note, My cams are machined as they are the older ones, same problem as the WD bars are not machined and they are not the same exact length either, another reason to mark left and right.
Hope this helps
John
