Hmmmm. Gotta wonder how many of these wiped out cam lobes we keep hearing about are from a lifter that was bottomed out instead of pumped up, then another half turn on the wrench???? I do my initial lifter adjustment on fresh engines BEFORE I put the intake manifold on.... If I can see the lifter, I know where the plunger is at......

fine but with a dail gauge you would need two one on the lifter and one on the rocker ..no need to get that fancy .my ford friend all you need is a wire feeler gauge if it slips under the plunger and clip on the lifter then you know how much of a turn and the fine thread nut needs on the rocker Nut a 1/2 turn is good .just like any thing it takes some time if you not not have it you will in trouble
