"Normal" shocks in the 911 means either Boge/Sachs or Koni (and some Woodheads) shock absorbers, Bilstein was always the "sport" option, this means the "normal" B6 shocks (all green).
But Bilstein offers far more shock absorbers with different settings, and they're all far more stiffer stiffer than the "normal" green ones. I see you have a Targa. Here in germany most of the owners of convertibles & Targas recommend not to use anything stiffer than the green Bilsteins (sport option), some of them go back to from Bilstein "sportlich Strasse"/"sporty road" to stock Boge/Sachs absorbers (the softest and stock with no sport option) because the body of the car suffers too much over time...Kayaba also proivides shocks for the 911 G body cars, they're a stock replacement (no sport option), in the rear for all G body cars,
but in the front only for Boge struts available:
They're worth a test.
All Bilstein shocks for G body are B6 (what I know). The colour on Bilstein is not useful to separate the shocks, only on the back: Green = Bilstein stock replacement = Porsche sport option, Yellow = Bilstein sport (any!). Boge/Sachs do not offer sport settings for the 911G from what I know. B8 are for coil over replacement.
Also be aware about the different meanings on "sport options" here:
-Porsche stock (no sport option) => Boge/Sachs/Woodhead
-Porsche sport option => Bilstein B6 (all green, but Bilsteins stock setting)
-Porsche Club Sport => also Bilstein B6, but stiffer setting, all yellow, this is one of two settings Stefan Rosar figured out on the Nordschleife in the "Yellow Bird"
-Bilstein "sportlich Strasse" (front green, rear yellow) => far more stiffer than "normal" Bilstein, often recommended here in Germany, but more and more go back to "stock" Porsche sport option (bilstein all green) or even Sachs/Boge...
Please refer to the Bilstein catalogue (the 2019 version linked here is the only one which contains most of the settings):

See pages 46 and following for Porsche, the values for the settings
And here's an overview I created last year about the different settings of Bilsteins:
