they pull your stock heads, use a dummy head with a drill bit shaped like a valve and put it in the guides of the dummy head for no damage to your heads guides. torque down heads and drill away till you reach the right depth for proper valve clearance. the area removed looks like a smiley face
) where the valve relief is created.
