You can see the top oil hole (arrow) in this view. The pushrod inserts can be changed for center, left, or right offsets for custom valvetrains. The insert also features oil control that allows you to increase the volume of oil delivered to the top end in applications that need it. The Elite Race lifters are also lightweight, reducing overall valvetrain mass. The only drawback is that these lifters cost between two and three times more than others.
