I'm a big fan of nitrided camshafts when the application is mild and a roller cam/roller lifters would be excessively expensive.
No experience with coated lifters, or how they interact with a nitrided camshaft.
EDM hole on a hydraulic lifter is a no-go. EDM only on solid lifters. "I guess" a guy could groove the lifter bores, but I have no plans for that.
