I have 255's in both my big twins. I've been very happy with them and they make a very noticeable difference.
They are not the same cam as the HO103 motor came stock with. The timing and duration is pretty similar, but they have much more lift.
There's plenty other cams that make more power, but the 255's are no slouch and can be had very inexpensively as guys swap them from their CVOs, where they came stock.
I think your performance goals mirror my own when selecting cams, and I couldn't be happier with the 255's.
Thank you so much for your input and the graph of power results.

Looks like the 255 is making similar power as a stock 103HO. The 255 S are great cams and would be an upgrade prerushmore bikes but to similar on a rushmore bike. The cyclerama or woods would be an upgrade IMHO.
Here's what you can expect with your combo, if you decide on the woods... And Cyclerama's are even better. They come on earlier and carry out longer, with higher numbers
Here is my concern, Fuel Moto gets just as much power with a stock cam on this set-up. I guess it is, all in which head pipe one runs.
Different bike. Different day. Different operator. Different heat and humidity... comparing overall numbers is pretty useless. Also they are in the buisness of selling their own exhaust.
What Wes Brown @ Cyclerama sent me from about the CR570-2 and the 575 cams when I was trying to decide, I told him no head work and he sent me the 570-2 I am very happy. Its a different bike.
Barry yes you can purchase the cam from us
Here is a dyno chart of a HO103 with our CR570-ll cams before and after

I am throwing the idea around about getting cams for my 16 SG. have everything I need for stage 1, I just haven't put everything on yet. While I got the bike on the lift, I taking off my remaining chrome covers and getting them powder coated. This includes the cam cover and the top and bottom rocker boxes. I am looking at the screaming eagle 255 cams. I will also be putting on the HD air cleaner and the Vance and Hines power duals. I have the HD tuner that is no longer available through Harley thanks to the EPA... I will be doing the work myself so I am not worried about labor. I am looking at $715 for the cams, solid pushrods, black push rod covers and black tappet covers.
I am not looking to make her a power horse. I am not wanting to bore over, or get a 110 or 120 motor. I just want a little extra out of stock motor and be able to enjoy riding. I ride a mix of back roads and highway. I don't feel the need to go mach 5 with my beard on fire. I enjoy the ride.
My question is... Is it worth it? What kind of power gains should I expect from all this and is it worth the money to get the cams and kit? Thanks, all. I appreciate your time reading and responding to this.
Is it worth it? Yes. SE 255 not so much. I like your V&H choice. HD Tuner. Not so much. PV way better, Solid push rods definitely not so much. See advice is post #6

A very nice drop in cam which gets overlooked,,and which your HD tuner has a map for, is the SE 204.
The 204 will take some of that overkill torque you have at low RPM's and spread it evenly from between 2800 RPM and 4500 RPM. This makes for very even torque from 0 on up and gives meaning to 6th gear which the OEM cam relegates to gutless overdrive function.
I have the 204 in my 2014 BO and I'm really impressed with the oomph I get from 2800 RPM on up. This would not be a good cam, however, if you like lugging away just above 2 grand like some riders do. I believe the 255 would be a better cam for that.
Oh,, the 204 has a relatively large overlap so you get a lumpy, lopey idle.
