Profile-specific fitting requirements
Performance valve springs are required. Performance spring retainers are required. Fitting the specified hardware requires machining. Measure the assembled valvetrain geometry before selecting pushrod length. For an automatic transmission, Crow specifies converter stall at or above the lower end of the cam’s operating range. Fit the DG4 oil-pump gear.

Installation and BBT support
Confirm the actual engine capacity, cylinder-head design and induction system before ordering. The installer must check cam timing, piston-to-valve clearance, spring installed height, coil bind, retainer-to-seal clearance, pushrod length and rocker geometry. Hydraulic preload or mechanical lash must match the selected profile. BBT can help assemble the engine-specific package and arrange installation and calibration.
