Default 540 pump gas motor tuining

Hello to all that can lend some advice, I am trying to tune my street car for the street . The engine is a 540 bbc with flat top pistons compression is 9: 6 .1 . cam is a solid roller .314 duration and .730 lift, cam is degreed at 106.375/ . the heads are brodix bb-2 plus that have been ported and flowed int at .700 = 377 ex at .700 = 297 and i am using quickfuels 950 pro series carb with mechanical secondaries. Primary are 82 secondary are 86 . trans is a turbo 400 with a 3800 stall and gear ratio is a 4.10 with 31 tall tires. I am trying to tune this car for street driving and would like to know if it would be better to lock out the distrutor at 36 degrees or dial the timing in using the springs and bushings from msd ? THANK YOU TO ALL THAT CAN HELP
