Consider the motor has gone up in size considerably.
The TTS 100 was a fine torquer cam for the 110, 9.3:1 compression, all done at 4500 or 5k in a 103. Now at 117 a 240 degree cam is what will get it to 5K or a little better with stock heads with good low end torque, compression adjusted accordingly, and no pms.
The TTS 100 is too short for the 117 which stock has over 10:1 compression. PMS will ensue.
The S&S 585 is a move the wrong way with its added exhaust duration, still a hot rod cam in a 117"
You may be surprised how sweet a Tman 600sm works in that 117 motor without head work. Don't let the lift fool you this is a short cam but just right.
I would not mess with the heads unless it is just a blueprint to install better guides, springs, seals and a serdi valve job.
