Looking for advice on a starting point on tuning.

My car cleans up fine with 17 initial and 35 total. My next combo im gonna run a solid roller and I will go further with dialing it in. I have a digital 6 box and it has a start retard feature built in so if Im ever not lazy I could utilize it. The best way to find your engines happy spot is using a vacuum gauge and advance it for highest vacuum.
