What to adjust cam gear to with B cam?

I have a B cam and a STS adjustable cam gear in my b230f 8v.
I am just wondering what I should set my adjustable cam gear to so that the car is timed correctly. Currently it's at 7 degrees advanced (which I've been told by multiple people is a lot), and I was just wondering what it should actually be at. I've been told be a few people to just set it to zero, but at this point I don't really know. When we first put the cam in, we set it to I'm pretty sure 9 degrees advanced (honestly idk what we set it to, but we just set it to the same thing as my dad's car that has an A cam in it.) The car did run last time we started it, but it was very choppy (could just be the B cam choppiness). I know I need new engine mounts, which probably doesn't help with the amount of engine rock, but it seemed like a lot of shaking. Help/advice would be greatly appreciated, thanks!

This is currently what it's set to:

Please remember that each of those marks is 2 crank degrees, which is what you're dealing with when people say "it's 2 degrees advanced" or "it's 4 degrees advanced". Basically what I'm saying is move it one mark at a time.
That is good to know, because I definitely thought each mark was one degree.
 
stock engine?
non turbo?
auto trans then advance it slightly.
manual trans straight up is usually best for A and B.
 
CT tuning did dyno tests with different standard camshafts on a unmodified 530 head. Volvo did a good job and there is no need to adjust the cam angle on a stock engine. If you want to change the power curves you should do so by changing cams.
The B cam is nice and it should not be choppy. Try a standard cam gear, you won't be doing any magic tricks with the adjustable cam gear.
