DLC Coated Lifters

DLC stands for Diamond Like Coating. That type of technology is not new and is in use in various industries such as aerospace, refineries, and pumps. It used to be very expensive and was used on parts that were expensive to produce and replace. It seems the price has come down enough to be offered to the more common race car owners and engine builders.
I would bet that the pro racers are already paying for it to be applied throughout the moving parts of their motors to increase the efficiency and to allow parts to last longer.
Here is some information on it if anyone is interested:
