Interesting how things change......they used to be 180's? As for the hole well I was told By BDR to drill 3 eighth inch holes in mine to help with the cooling issue. I drilled one as I live in new england and drive it in spring and fall. The one hole helped but was not a cure, plus motor would not come up to temp on cool spring or fall days.
So I installed the enhanced radiator with a 180 stant and no holes. Motor now idles without going over 190 and the fans actualy cycle on and off not staying on 100% of time.
Personaly I don't think lowering the temp of stat on a street car or drilling holes is a wise option. JMHO
