Neighbor just finished an engine with a Comp Cam and their lifters and lost two lobes on the 20 minute startup. Called Comp and they sent him a new cam and recommended the DLC coated lifters. Said the issue is really with lifters and not the cam. He totally rebuilt the engine and used the DLC lifters and all is well after run in and several hundred miles. The DLC lifters have a mirror finish on the bottom and don't really seat in to the cam. This was a small block with Z28 level valve springs so nothing over the top on spring pressure.
