Rhoads haters will always hate & badmouth Rhoads lifters, just like "qudrajunk" haters will always badmoth Q-jets & tell you how much better a Holley is.
Lots of us have used Rhoads lifters for 40 years or so, with good results. They have been well proven by thousands of guys, for a long time. We won lots of races with Rhoads lifters and Q-jet carbs. So, it all depends on who you ask.
But, if you don't like Rhoads lifters and/or Q-jet carbs, just don't use 'em. Use something else. But, there's no sense in badmouthing something just because you prefer something else.
Jim Hand and Cliff Ruggles are 2 well respected Pontiac guys who have successfully used & recommend Rhoads lifters. They have dyno & drag strip testing to back up what they say. Rhoads lifters work exactly as advertised, to extend the power range of the cam. They allow you to use a slightly larger cam than would be possible with regular lifters. They smooth out the idle some, give slightly more vac, and probably more torque, under 3000 rpm.
It's always been rather comical to me how some guys say they really love the way a solid lift cam sounds at idle, but then you hear other guys say how they just can't stand the minor "ticking" sound the Rhoads make. If you have a hot rod, with a healthy sounding exhaust system, you can hardly hear Rhoads lifters at all.
But, for the Rhoads haters, there are several other brands out there. You can have quiet lifters & a quiet exhaust system if you prefer. Roll up the windows, turn up the AC and cruise. Different strokes.
