A Close Look at Speedmaster's Roller Rockers

From the hole behind the roller (which im guessin' is there;-). Tap that top hole for a #8 set screw.

Hey all I went to take a look at the rocker and there's no hole on the bottom side

If take a look at the Comp Cams magnum rocker, it has the same type of oiling hole.
