the only part I questions is matching all the parts up. He take's apart all the lifters and puts them all in a gal. bucket of carb cleaner. He states that the parts can be mixed up and put back together as long as it is done only a few times. I have always been told to keep them separate so each part of the lifter goes back as a set, that they started from. I know this is a pain in the ass when doing 24 of these. Any insight on this ?
