Can anyone tell me the pros and cons of tool steel flat tappet lifters? Looking at Howards tool steel, extreme duty and their lite weight lifters. all have direct oiling, but i'm really interested in the tool steel if they don't cause any issues with cam lobes. Thanks Dont do it , the reasons that Dwayne describes for my failure is IT. https://board.moparts.org/ubbthreads/ubbthreads.php/topics/2402051/flat-cam.html
