"The ht2148 sealed power lifter works. With the ford style dog bone and a .335 lobe lift the barrel does not come up far enough to hit the dog bone. This would become an issue if you added another .040-.050 lobe lift or more. Just more info."

I was using his number, assuming that was the V6 part number.
