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

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...

They oil like a big block except the big block gets it oil off the number 4 cam bearing to both sides. The small block gets oil to the shaft on the drivers side from the number 2 cam bearing and the passenger side from the number 4 bearing.
