MRL Roller Lifter Street Durability

I have 100% faith in the lifters Mike developed. And in OU812's for that matter. What I worry about is race technology in a street car being ignored like most street engines are. Race parts are normally carefully set up, looked at regularly, and looked after. So as long as you make sure the setup is right from the start, and keep looking to make sure nothing's changing there should not be any problem.
