The rev kit forces the lifter to follow the cam profile at all times, and any lash that is used in the system is upstairs from the lifter.

From someone who is a big proponent of street rollers here's my advice:

If you don't want to run any given part for any given reason, then don't do it Do whatever you deem the best plan for you and whatever gives you a decent amount of confidence.

However....keep in mind some people run around on the street with 15:1 compression and aluminum rods....yet they won't use a roller because of perceived reliability issues.
As if what they already have is going to last forever

Everything we do to make more power has some sort of potential reliability sacrifice. It may not always be enough to notice, but it's always there. To think otherwise is kidding oneself.

It's all good, build your car/engine any way you want, the important thing is to have fun with it.
