Keeping the rockers and valvetrain rock-solid and locked in place is achieved by using Jesel stud girdles made specifically for the SR-71 heads, along with a set of Comp Pro Magnum roller rockers. The hydraulic roller cam is a Comp stick that comes in at 255/270 duration with lift of 0.675-inch on a 108 LSA. You can also see the ARP hardware used to keep it all together.
