And part of the reason the engines needed a rebuild at 100k or less.
There is a reason they move to the 195* and engines started to last 150k+ without trying. But whatever works for you is good.
I tend to think the group of factory engineers might just know more than me.
And when the outcome produces longer average live spans, with no down side. I tend to use it. Your build has a bunch of later model features added because they are better than what was offered originally. So who am I to question your opinion.
Did you put a temp gun on the hot side hose to know what temp it was when the gauge showed at the hash mark? I have 2 oem temp gauges, and they don't read the same, one shows 1/8th" difference in where the needle sits when warmed up, than the other gauge. So my trust in (at least) my factory gauges is nill.
