Most cams you mentioned would give you about the same bottom with more midrange and top end,probably not what you want. I don't know what you want to spend,but a good tune and some lower gearing would probably do the trick.A step up would be the woods 222 or woods tw5-6 and up from there add a little headwork. Don't get talked into overcamming,it's a tourer,not a hot rod........

Our riding styles seem very similar, I went with Fullsac stage 2 sleeper kit on my CVO Ultra, it uses the Andrews 54 cams and makes nice power. I'm very happy with it and the customer service is top notch. A lot of guys on the other CVO Forum run the same kit and I hear nothing but good things about it.

I have a 2013 CVO I'm looking at build options. I spend hours looking at cams and Dyno results.....
I decide that I might be interested in doing cams, the comitec .030 head gaskets, and port and polish the heads.
I talk to a builder and tell him what I'm thinking about doing, I tell him I'm looking at Woods TW-222's, Mackie 575's, and the Andrew 54's. I ask him to consider these and make any recommendations he might think would work for me.
I tell him I'm looking for improved performance, I do 2 up riding, hills, back roads, and am thinking I like low and mid range torque. but will do some highway riding but don't need to run 100mph all day.j
He comes back talking about S&S 570's. He adds that we are going to have to deck the heads to bring the compression up to right below 10.
Is the 570's a good choice and should it run well on my bike ? I have power dual, monster rounds, and a SE Pro Tuner.
It seems to me by selecting a 570 he's creating a need for more work to make the 570's work well. Wouldn't a different cam choice be better or is this guy really smart

You have a decision to make .
Do you want to bolt in a cam?
Do you want to do head work and use a cam to take Advantage of the head work. Doing head work to a 255 or 222 is wasted money for the most part . Those cams will never pull any hp. And it is hard to increase tq below 4000 rpm over the stock heads and 255's.
So if you want more, the gains are going to be over 4000 rpms.
What you try to do is , build the motor with more compression with a later hitting cam, so you cam make hp. If you do it right you can keep the same bottom end power and increase the top end hp. It isn't hard to do once you know how these motors work.
The 570 would work decent as a bolt in and even better with compression and head work.but as far as I know it is still a gear drive only cam.

He is right the 570 would benefit from compression. The 222 is a bolt in .

But if your pulling the heads , now you need to decide if your porting them or just surfacing them? If you port them , then there are way better cams to use.
If you just surface them, then that's a lot of labor if a guys is paying for labor, just to set compression. But you save the money of porting. Diff ways to look at it. The 110 heads throw a twist to the mix . They will make some big tq un-ported. To make hp they need some work to get that extra 10 hp.
So short cams work good in them stock , because it increases cly fill.
If you want a good bang, by just surfacing and increasing the compression
a little , use a feuling 574 and take the heads to 91 cc's
These 110 heads like the lobe seperation,and the intake/ exhaust centerlines of the feuling cams.
