Is it ok to / any draw backs to switching out a set of solid roller lifters? I know the flat tappet lifters need to stay matched up to their lobes if pulled. But ordered a spare set of solid roller lifters, thinking about putting the new set in for the rest of the season and sending set that's in the motor in for a check up over winter. Need to do a valve lash check before making the decision. . . but wanted to ask the masses before I do.
