How often do you need to have the roller lifters rebuilt in these retrofit applications? Not all of us need that last few horsepower and want an oem type lifespan. I wouldn’t want to pick up a new winter maintenance item unless it’s a last resort. I can’t imagine a stock rebuild would net out much by going roller anyway.
I think that would depend on how many miles you put on and how aggressive the cam is. I only put a few hundred miles/year on and check lash every few years...zero issues(mine has been together roughly 10 yrs). Going roller wasn't about every last HP more about OEM longevity. Every pushrod V8 built since the mid 80s has been roller cam equipped......millions of miles proving rollers work.
