Sometimes the rocker arms wear where they contact the top of the valve stem. Because the feeler gauge bridges the wear it gives an incorrect clearance which could be much more than the feeler thickness.

Us old fellas would adjust such tappets by feel without a feeler or using the picking from a cigarette packet. The old ones were just right.

Check your rocker arms.
