Lifter Technology Selection

What does "the maintenance" mean? I figured the oem went to rollers because of (among other reasons) a reduction of maintenance.
Also, what does a Solid Roller Lifter on a Hydraulic Lobe do? I have heard of doing this, but wondered why it is done.
I am interested in knowing more as I will be going down the same path in the not to distant future (hopefully).

Maintainence means really clean, quality oil. Constantly keeping track of lash and spring loads.

Yes, guys will come along and say they never touch their roller junk. Either they are lying, or a decent flat tappet would smoke what they are running.

You can run a hydraulic lobe with a solid roller and lash at .002 cold and they work. You still get all the bullshit of a roller lifter though. At least you can run some spring pressure to help the valve train not kill itself.
