Cam Break in Question

No I've never had this problem on break in. Sounds to me like the heat treating wasn't done right. A 130lbs on the seat and 320-340 open shouldn't hurt any cam. Stock springs are 100-110 on the seat and 270-290 open if the springs are worth anything. In some cases you may have to take the inner spring out but you shouldn't have to on a cam like this.
