After my upgrade
Just did a top end 103 build on my 2008 FLSTC. Ported polished and CNC heads to 10. to 1. Flat top S&S pistons. Bla, Bla, Bla. And for the cam I went with a Chris Rivas ez start 584. I have a SERT tuner. This was the right cam for my wants, FAST and a lot of TORQUE!!!
I went from a SE204 96" to this.
The before is a down load, good guess too! Then the finale. The cam is a hipper one for sure!

Your torque to cubic inch ratio is really good. 1.145!!!
The ultima el Bruto 113ci gets 120 lbs/ft and thats the most powerful crate engine ratios around so yours are excellent

Posted this sheet in another thread, but not in the Dyno thread. Sheet shows difference between the old Tw6g cams on a 95" with worked heads and larger valves compared to the current HQ39g cams with worked heads and stock valve size. had been been trying all kinds of exhausts trying to improve low end power and finally decided to try another set of heads. Not sure how the tw6 cams would have run with the new heads, but was not willing to pay another $400 tune if I wanted to try the HQ39's later, so I just installed the 39's. Nice improvement in low end torque - kind of surprised me since I dropped compression from 10.5:1 to 10.1 when installing the new heads. The yellow hashed areas are improvements with the new heads and 39's.
