Are you comfortable with 14.5V?
I recently did the Denso swap on my SB... new AutoZone. I had a first one... that was reading around 15V.
I've just exchanged it (lifetime warranty)... reading 14.5V ... and when I put on the headlights... 14.0V... heater motor full blast... together (lights and heater)... about 13.5V.
So, is 14.5 OK without any load?

IMO, 14.4 is perfect with a small load. The real question is when pulling 30 amps or more, plus whatever the battery is charging soon after starting, what is the Voltage at various rpms?

So, is 14.5 OK without any load? there are some Denso replacement voltage regulators with a 14.9v set point. i got a rebuilt 65amp alt for my old truck and it runs at 14.9v. kinda worried me until i did some research on it. seems 15.2v is about the limit for factory electrical parts so i haven't had any problems with it running 14.9v.
