You're certainly justified in your confusion. I'll throw out my understanding, and will let others poke holes in my theory.
The B8 has a stroke (length of the piston) that is similar to the factory Monroes, and shorter than the B6s. This does not mean that the car will sit lower when on the ground. Instead, it means that the top of the spring will remain in contact with the car when the car is on a lift. This is important to some owners where a gap when the car is lifted would cause an inspection failure.
The B6 has 2 differences:
1) The stroke is longer - you may get a gap when some springs are unloaded.
2) There are more threads on the shocks, so you can further lower the spring perch on the shock body, therefore lowering the ride height.
You guys that know suspensions - please read this and poke holes in it.

Here is an old post by Gert that sheds some light on it. Seems most people equate HD's as B6's but you can see B8's called HD (which just stands for heavy duty) too. Too avoid confusion I think maybe we should say "B6" or "B8" instead of HD. Then there are 2 versions of the B6, euro and north america

Bilstein B6 for the 993 have always been called HD (heavy duty).
The B6 for the US market always have the extra threaded fronts ("invented" by Carnewal btw).
B6 offered by the RoW dealers always have the limited threads on the fronts and is what we call the "normal" B6 shocks.
The B8 for the 993 has the same damping and threads as the "normal" B6, only the piston length is 20mm shorter.
This to eliminate the floating spring problem that might appear when you install shorter springs like for example the M033 springs. Mainly in countries with a strict yearly technical inspection like Belgium and Germany, inspectors don't like to see loose springs when the car is on a lift.

Not silly at all. Especially if you are in your return period little things like that drive me nuts, something I prob need to work on....

My ride height is either RS+5mm or RS+10mm, whichever is halfway between RS and RoW Sport height. I can't remember and Rockit's post doesn't have the RS height.

Here is a pic of stock U.S. springs top and euro spec ROW now with the B8's and MO33's below.
Handles better and does not bottom out....looks MUCH better.
