A compression test would be the first test I would start with, If you have low psi readings in the suspect cylinder your valve could not be opening all the way. To replace them you first have to remove the valve cover then the rocker arm and the push rod, then you can take a telescoping magnet and pull out the lifter. Turn the engine to top dead center and mark the distributor where the rotor is pointing. Remove distributor, fuel lines, the intake manifold and related wiring. Now you can remove the retainer for the roller lifters and replace any bad lifters. Assembly is reversal of removal.
