Bro you are giving me way too much credit here. I have no idea what those acronyms even mean so it's not even possible to get started with that list. If I saw my model with the equipment I am running named, sure, but I can't even discern a starting point from that link. And yes, I tried.
Whoa, if that's where you're at, and there's nothing wrong with it, you shouldn't be asking for cam advice. You need to start from the beginning and read up so you can not only talk the talk, but understand also. There's a world of knowledge out there and people here willing to help, but baby steps bro.
Can you tell me anything based on this? I keep looking for the maps you guys use from your dyno but this is all I could pull off the PV. I worked from the canned tune and settled on this after about 10 rides, but didn't like the last few edits and stayed with the 7th or 8th. There's also a 3D model that looks like a tabletop mountain in rainbow colors but I wouldn't know how to go about importin that image since it moves.

I'm running the V&H Big Shots knocks-offs by Python and an open backed air cleaner along w/ the 30/70 pulley, have a PowerVision, so the basics have been addressed. I know I would like to be able to hit 90mph without beating on my motor too much, which I understand simply as 3400-4000rpm is too high for any extended period and you should always shift up when you hit around 3000rpm. As far as what do I want out of cams specifically, to be honest I'm not certain. I know different cams have different benefits so that's what I'm asking about.
Others may chime in on this, but I respectfully disagree with your RPM limitations... The Twin Cams don't mind RPMs...
I have 4 Twin Cams and live in SoCal where freeway speeds often reach 80 mph...
I routinely cruise above 3000 rpms.
I have '03 & '01, 5-speed, Twin Cams. They cruise above 3K all day on the SoCal freeways.
I have a '16 Bagger with a 124" crate engine, and a 32T solid front sprocket. This is my trip bike. I have cruised that at 3400 rpms all day and it just hums right along.
I would probably re-gear if my usual cruising rpms were above 3500 RPMs, because that would just eat a lot of gas....
As already mentioned, the gearing controls your RPM range, not the cam.
The cam will dictate where the power curve lies. It will influence gear selection based on that power curve and your cruising style. However, it's the gearing that decides how fast you go for a given RPM in a given gear...
Unless you change the gearing on your bike from OEM, choose your cams based on matching the power curve to the RPMs you use the most.... On a 6-speed bike, you can cruise 85-90 all day long and will be fine with your RPMs...
Good luck with your decision....

Two 103's of mine; I still have the second, lower power one. It's EFI and much more suitable for touring. I also really enjoy the S&S E-Z start cams...stock starting system and never any problems, even on hot summer days. Choose careful. Fuel Moto is a good start. I have other resources where I live way up north.
This whole thread is based on the incorrect assumption that a twin cam engine should not be run past 3000 rpm.
This is simply not true, 3000-5000 is the sweet spot for these engines, 2500 is borderline harmful
You know when these were newer I asked, often, exactly what RPM range was safe. What specifically, in numerical terms, would constitute lugging? Nobody could answer it suitably. Because the 103 did seem to perform strong well above 3000rpm but as most owners who have done the pulley conversion agree it didn't perform correctly with the awful tall gearing. I've always gone by the rule that if it pulls it isn't lugging.
