I also use the EOIC method, I have a starter button on my radiator support, and they make feeler gauges with two sizes on the tip, so first size is snug and the next size will not go through. Temp is a bigger factor, if you start on a hot engine, most specs are for hot lash, by the time you get to the other side how much has it cooled? I set them cold on the engine stand, then check when warmed up, noting the difference, and then calculate a cold setting I use from then on. I use this chart from hot specs on the engine stand cold.
