The Crower 60919 and RAIV cam as basically the same thing, so expect the same results with either one. They work fine without the Rhoads lifters, ran my old 455 w/o them for quite a while. When I finally added Rhoads lifters to the cam vacuum at idle increased 2" and it also improved throttle response right off idle.....Cliff
