[funkatation]

Mine were installed last year and it drove me nuts. I was told the lash, the weight of the oil, it needed more miles. None of it fixed it. Hydraulic rollers are supposed to be quieter than flat tappets. I haven’t run the engine with the new lifters (they are Johnson ones) but I think a lot of it had to do with how the bbc oiling system works. These Johnson ones are said to do better with less oil. I was told to run lighter oil with the morels, which went against my engine builders recommendations for the rest of the engine.
