LA small block,Do you put an oil passage in your head stud?

It's been years since I've had any small block heads, so I didn't remember how the hole was routed. That's why I asked.
i was curious about this too, quick google search and i found a good photo, see the third photo from top. looks like the passage turns from the deck into the head bolt and i guess another angled passage up top that send the oil to the rocker stand...
