Roller Rocker Lifespan

I am rebuilding the 400 in my '79 f250. When we rebuilt the engine last, about 70K miles ago, we put a set of Motorsport roller rockers in it. It was a mild build with a slightly bigger cam and stiffer valve springs. Nothing has failed in the engine. The pedastals all look good, no wear issues in the rockers. My question is what is considered a normal lifespan for aluminum roller rockers? Is there any reason not to put them back into the engine?

If it were my engine, I would put them back in. "No wear issues", I don't see any problems.

I don't see any problem with reinstall them just check the rollers both the tip, and trunion for looseness and if no slop run them. On a mild build they will last every bit as long as a stamped steel rocker under normal circumstances.
