I thought i had ordered both 160 and a 180 stat.
But when it arrived its just the 160.
Guessed clicked wrong
Put it in yesterday. With new radiator hoses. Refilled with same distilled water and wetting agent.

Fired it up in the garage .....And the temps stayed in the 170 ish temp range at idle speeds. For over a half hour.
Will be driving it this weekend and will see how it does on the road.
