Am I reading your post correctly? You screwed into and through the rocker cover, releasing dirt into the engine?

I know there are a host of different ways of securing a rocker cover, but I thought you were talking about air pipe/cleaner retaining bolt threads in the rocker cover, not screw threads in the head. I'm totally confused. I need a photo.

That's a very old design indeed. Not too many rocker screws go through the open breather space in the rocker cover any more. The cover tends to flex too much with these designs, which often leads to early leakage around the rocker cover gasket area.
I wouldn't worry too much about it though. They couldn't have been that dirty could they?
