Good luck in your quest for the real Harley. I went with the V-Thunder (Comp Cams) TC-3102 when I decided it was time for cams. It seemed the closest to the Kury TC-24d cams at the time, which I had a TTS map for. Both of those cams appear to have been discontinued since then, but are apparently similar to the 57H. I absolutely love the cam. Beware it will make your exhaust thump much harder. Might be a problem if you wear a full face helmet, depending on how much your exhaust resonates. Something with a big power chamber might be like BOOM BOOM BOOM in your head.

Generally recognized that short shot exhaust sounds nice but absolutely kills low and midrange torque. It would be a shame to build a great motor and then give back all the gains with a bad choice in exhaust.
I had short shots before I went to a 2-1. And the sound and power difference is noticeable.
I started off with just wanting to do cams and then ventured out from there. Since it's been taking a couple weeks to get my cylinders back, I've been looking into other things to do while I have it ripped apart, changing the exhaust is one of the things i've been looking at. So that might not be an issue anymore.

Maybe a larger throttle body from HPI? https://www.horsepowerinc.net/throttle-bodies

Maybe. HPI throttle body is around $600 and head porting with CNC is around $800. 06 heads are very good with flow. Don't need more lift, but larger valves can help some more. If I only had one I'd do the throttle body because doing the heads does you little good past small gains from enlarging the valves without replacing the throttle body. Either one has a fairly large cost though with minimal gains. Do both and you maybe get another 10 HP.
