08 Usually at full lift there’s not any coil bind when using the recommended springs. It’s still good to be sure there’s a minimum of .060-inch between the middle coils at full-lift. It’s also important to break-in new springs. Never initially run an engine at high rpm. Limit rpm to 1,500-2,000 until it reaches normal operating temperature. Shut off the engine and allow the springs to cool to room temperature. This helps eliminate early breakage, and prolongs spring life. We rotated the engine over dozens of times while assembling the valvetrain and setting the valve lash. Comp’s crank tool socket (PN 4799) made it easy, plus it incorporates a knurled retaining nut that can sandwich and hold a degree wheel in place. The valve lash calls for settings of .016-inch intake and .018-inch exhaust. We rotated the Wedge enough times to re-check the lash at each valve about five times. Yes, we’re nuts!
