12. For lifters we are using Comp Cams short-travel hydraulic roller lifters with link bars. The Comp lifters shown on the right have no lifter bar and are regular travel with a stock Gen II style lifter guild. The reason we wanted to go with short-travel lifters is that they generally can take the higher rpm's without pumping up the lifter causing improper valve adjustment. The short lifters are a great addition to anyone who wants to autocross, drag race, etc., without having to go with a solid hydraulic roller lifter.
