Head gasket recommendations for magnum

Is that with the springs you use and zero lash?? Something isn't making sense to me, but that's not unusual.

No I just put the dial indicator on the lifter itself, not the center but top ridge of the lifter and measured how much lift by turning the engine over until I reached max lift then multiplied that to the rocker arm ratio of 1.6 which I’m pretty sure thats the ratio these magnum engines have unless I’m mistaken.
