LS SPRING HEIGHT
Measuring installed height on LS or any other engine with beehive or small OD retainers can be tricky without a special height mic. But if you take your standard height mic and flip it upside down it will work. You will likely have to take a measurement without the locator installed, so just subtract the locator thickness from your reading.
