Resurfaced lifters

Hell anytime I've taken a lifter out there was not much left to resurface. The engine is worn out and full of metal anyway. Why spend all that move and reuse a lifter?
In my case I was like I want this massively radical cam and that's what they ground for me LOL and then four or five hundred miles later when I said this damn Cam's too damn radical! LOL they re ground it a little less radical and touched up the lifters for me...
