Some 5.9 roller cam help from y'all please

They have been around since the 70's at least.... they do what they say: reduce duration at lower RPM's. Just noisy from all I have ever read.....

The Rhoads lifters will not help your lift so I am not sure if it will actually make what you have into a torque cam and it won't increase overall 'poop'...... Do you have the stock cam? Can't see it doing what you want at all really......
