Note that other componant that leaks oil onto the headers are the spark plug tube seals - each tube (6 off) has 2 rubber O ring seals (12 off) which often leak after a few years use. They can be changed out easily and the seals only cost a few $$$ to replace....
Maybe these are what the shop tech is alluding to.
