There is alot of answers to that question.
If the engine is STOCK, more then likely the locking nut that holds the rocker arm on is wore out. ( Not locking ) Replace Locking Nuts and adjust them correctly. You could also have Camshaft lobes are the bottom of the lifters wearing too.
If the engine has a high lift camshaft in it, Then it may be pulling the studs out of the head. The studs are what the locking nuts screw to. WE really need more information on the type of engine and whats been done to it. There could be other things going on too.
