I also looked at them when I ordered my Bassani...
Stock flange are already stainless, I Wonder how much can they be polished.
I put ARP 12pt SS nuts on them.
CG, just curious, why do you shoose the 6 point nuts ?
I though that only the 12pt and "small flange" 6pt were 300 series, not those ?

The nuts are ARP# 400-8614 (6pt, 3/8" hex, .612" flange) which are made from "ARP Stainless 300". That's their trade name for 17-4PH. It's supposedly a proprietary alloy, but the specs I've been able to turn up are the same as 17-4PH.
I chose the 6pt just in case I ever have to get an open end wrench on them. Access to the rear nuts can be a hassle and I wanted to make it as easy as possible.

Maybe it's year dependant for the stainless ? My OE TB flange are in the same material also.

I agree. I'm gonna be kinda bummed if the new stock flanges are stainless.* I'm not concerned about bling.
My 99 flanges are a little rusty and warped. It's entirely possible MoCo made improvements over the last 20 years.

Good Bling: Adds pleasing aesthetics without compromising any functionality or adding unnecessary weight, and often actually increases functionality and/or durability, and possibly even reduces weight
Bad Bling: Stupid doodads that maaaybe somebody thought looked good at some point, but add no functional purpose and often add weight, clutter, clatter, visual noise, and overall stooopidness
