Is a roller cam worth it?

So compared to a typical $65 – $75 set fo flat tappet lifters, a set of roller lifters is going to set you back a bit more $, but in the end, for what you gain in performance & reliability, it is well worth it.
Is a roller cam better than a flat tappet cam?
The flat-tappet cam lobe is more pointed at peak lift, while the roller cam nose tends to be rounded; this means the roller is holding the valve open at higher lift for a longer period of time, which results in a greater fuel/air charge. The lobe shape also opens the valve much faster.
Can you reuse a roller camshaft?

Do roller cams add horsepower?
We chose to not only add a hydraulic roller cam, but also increase the duration slightly to increase our peak horsepower potential. The first test immediately raised the engine’s peak horsepower point to 6,200 rpm from the flat-tappet cam’s best horsepower peak of 6,000 rpm.
