Base timing. Really ?

I set my 360 to 16° initial timing. Distributor is from fbo with limiter plate. Cam is the 292/508 mopar cam. Seems to start fine. Also runs well. Question is can I try more initial or just keep driving? Really only left this way since it came @ that setting since purchase. This distributor was used before with 280 mopar cam too.
I once ran that cam in my 367,A833/3.55s/68 Barracuda.
It liked ;
20* cold
14* hot
32 to 34* at WOT after 3200
5*@550rpm in gear and pulling itself
56* or more at 56mph =2600 on the hiway.
The only way to cover all the bases was with a dash-mounted, dial-back, timing retard, device. Mine is a Jacob's.
That combo was; 11.3Scr with ootb Edelbrock heads,, flat top hypers at ~.034 Q, and ran about 180*F sometimes more,eventually up to 207*.
I installed a two-stage timing curve that ran to 28* at 2800, and then slowed down to 32@3200/about 34* at 3400 and done.
