Brad head with stage 5 rockers

With a Brad head that has stage 5 rockers on the bottom side of the rockers are the holes supposed to be open or plugged?

 

This is our first hemi, we don't know how do we tell the difference?

 

If you plug them you'll cut off oil flow to your rockers. If your block has restrictors leave the holes open. If not, put restrictors in the stands. That way if you need to adjust oil flow you don't have to pull the heads to do so.

 

Do you mean the rockers by the pushrod pocket if they are blocked off that is a mod. to make the adjuster oil usually done by PSI
