Also it should read higher than the stat, no? Once the stat is open by definition the temperature is 160F or greater.

On my big block car I have a 180*F t-stat and the temps are 190*F on the top hose and 145*F coming out the bottom. This after installing the infamous $50 Taurus shrouded cooling fan, which moves 3000 cfm on low speed and something north of 4k on high.

Use the temp gun on your manifold or wherever your gauge sender is mounted and that will give you a good idea of your dash gauge accuracy.
