timing chain oiling

hey guys im installing a 360 magnum in my 72 duster. i pulled off the front of the engine and put on a mopar performance timing chain tensioner and double roller chain. i noticed that none of the bolts securing the tensioner to the block has a hole in it like the la engines do. how does the timing chain get oil? also there wasnt an oil slinger on it. is this normal for magnum engines?
Yes ,it is.
