6 of the lobes were rounded to the rear of the cam. Yes the lifters were oiled on the sides and spun in the lifter bores, also the flat surface of the lifters had break in lube on them. Yes the lifters were new, I tried a set of Comp Cam lifters #CCA-800-16 they have an oil hole laser cut into the flat area to supply extra oil.

Don't know what causes it, if you ask cam supplier they say 99.9 percent cam failure is do to improper break in, others say poor cam.
