When making a cylinder head change on an engine, it's always a good idea to check that the valvetrain geometry is properly set. This is checked by mock assembling the valvetrain with the pushrods (engine builders often use an adjustable length checking pushrod), and inspecting that the rocker tip stays on the center of the valve tip. Where the rocker tip touches the valve tip is adjusted with the pushrod length. White Racing ordered Comp Cams 3/8-inch-diameter, 9.650-inch long pushrods and they produced excellent valvetrain geometry. View Related Article
