Only you would catch that! It measures correctly by the radial hash marks but the vertical is a progressivley worse as you get past 2". Got it from Isky a while back. Do you have a favorite brand of spring height mic? It definitely 2.02ish.

The guys that were running these heads before me omitted and spring cups or locators due to only having 1.88" IH on a 1.625" spring. The heads aee very old so i imagine they have been through many hands.
