Are SE 255's still good cam choice

This is a 07 SG with SE tune, KN filter and SE slipons with Big City Thunder baffles.
I'm getting some engine work done due to crank run out which took out my oiling and my crank bearings and figured while in there putting the 255 cams in. Getting the work done thru the dealer and thinking they like their Harley stuff along with all the good posts touting the torque increase with them.
I'm not really high speed but love my torque. I can't do the 103 right now but also wonder if the choice would be the same so I don't have to pull that area apart again when I do have the cash to do the upper.
Thanks for any and all advice

I have them. They are OK, but there is much better out there. Mine will be coming out and swapped for something better. I think I will be doing the Wood 777 cams.

SE255 cam is the CVO cam. There's better choices. Scott (HillsideCycle) was just talking about this.

I've also heard the 255's make your bike a fire breather, i.e. run hotter and heat up the boys at stops.

Use the words "school bus" in the search engine. Scott said the cams produce a ton of low end torque, then go flat quick. Like a school bus......

Found the school bus post, I guess it all depends where the flatness is in regards to where I like it.
I was thinking SE cams would be what they might try to push but now I found out I will have some info from them tomorrow Don't know if they use anyone else's in their builds.
Are any of the better cams SE units?

Plug/play cams in a 96"er are the Andrews 48, or the new Wood 222.
We've seen 87/97, on our Dynojet 150 here,(carb only dyno) with the 48's.
Client had a PC autotuner, and a D&D Fatcat/air cleaner upgrade, and has never had it tuned. Loves it.

the CVO`s really need alittle more compression to have better cam choices & make decent power,we`ve set them @ 9.9-8-1 to 10.0-1,nothing crazy,and used S&S .570,andrews 54 & S&S .551`s (for low end torque builds) and had very good results

Well of course I didn't hear back Friday from the shop. Must be busy
Question, keeping in mind that I would eventually be doing the 103 or 107( from FuelMoto)would any of the above cam suggestions be better suited than others.
