Tom what I mean by preload condition is at tdc the valves are held .005 open. If I set them at zero lash cold at tdc to remove this I would have more lash than calls out on the cam card when the engine is warm. My other concern here about excessive lash is I'm running a set of all composite lifters and want my lash kept at the utmost minimum.
