Another timing question

Timing 41 ° total timing. 496 stroker bb .is this ok . Cars runs grate no vacuum advance hooked up. Was thinking of hooking up the advance for a better idle. Was thinking it would make it run cooler in traffic. Any input. Tuned on Dyno. ( not by me ) I'm kinda a layman when it comes to this stuff.
