If funds are available, the early heads need improvement. Plenty of places to have them worked BigBoyz, Hillside Cycles, WFO Larry, AKA Larry's Motorcycle and Machine and HD Street Performance are a few that come to mind. A dyno tune will be necessary with any of the above modifications.

Could always throw a -4 sprocket on there

I ran the SE204 in a 09" 96" streetglide. I know, slightly different motor, but was otherwise stocker with bub slip on mufflers and SE air cleaner. IIRC, made ~90 hp and high 90s tq. Nice lope to idle. The 204 has a lot of ground in advance but I'd run it straight up. Nice cruiser

South Texas heat brought out detonation with 190psi CCP and I had to replace the cam. We tried pulling timing but that just turned the bike into a turd. I still like the cam though; just have to set it up right and not expect more than it can give.
