RE: Disadvantages? Yes, cost.

There are reasons to fit roller rockers such as high spring pressure, and fighting for every last drop of horsepower. It's hard to justify the cost for an engine that doesn't need them. As to the claims of added horsepower...only on the right engine and even then it's very slight. In your case, the power added would be within a dyno's margin of error and, therefore, wouldn't be measurable. Roller rockers are more of a durability enhancement for high-rpm use than a power adder.

And everything mechanical will wear. You can only reduce friction, not eliminate it.

This thread, so far...
