Valves need adjusted. Some more often than others. The adjuster is mild steel will a point like a dull pencil. Smacking into the valve stem repeatedly flattens, and work hardens, that pointy tip. Early on, every five thousand, at 15, it wasnt so far out, I hardly did anything at 20. Now, seat (should it manage to seat itself deeper) and valve lip wear allow the valve stem to move toward the lifter, possibly losing the required lash. Oonce I feel comfortable about the seat, I adjust the valves as tight as I can, InsideSpecs. I bought a cam to increase fuel and air in and out, I WANT to adjust valves to help. It takes longer, because playing with adjustments and trying to get them Thaaaat close to potential costly errormeans checking, rechecking and checking again. The slack in the threads opens the adjustmen when the jam nut is tightened.
