To me one of the biggest advantages was NO chance of losing a lobe on break in! Been there, done that, never going back.
A roller tappet allows for a much more aggressive valve opening rate. This equates to more lift for the same duration and more area "under the curve". All of this means more power.
Going roller in an old block isn't cheap. My complete kit from Comp was $777 but if it's in the budget it is a great way to go.
