I've never seen the need for "cam saver" type lifters in one of these engines. With the open lifter bore area I've glanced down there many times while priming these engines and BOAT-LOADS of oil is running down on the camshaft lobes and the oil is still thick and cold.
IF you have doubts about lobe failures take the money not spent on those expensive lifters and send the cam out to be ion-bonded or "coated". Then run the Hylift Johnson or Rhoads V-Max lifters on it if you want a variable duration lifter that's adjustable for the amount of "bleed-down" at low RPM's.
Your cam will come back looking like it was chrome plated. It's not that expensive and without any oil at all has the lubricating capacity of 5W-30 motor oil. It will last just about forever and if nothing else you will sleep better at night.........Cliff
