Your present setting, 1° BTDC, is fine.
An old school trick is to place the camshaft at different degrees and crank the engine over and measure compression. The setting with the highest compression reading was optimum.
This is an old wives tale & absolutely does not work
Stop & think about it for a minute & you will understand why

Install the cam with the intake center at 106 & call it good
To do this find max intake lobe lift & zero your dial indicator
Recheck a couple of times to be sure you have a good number
Back up about 60 thou
Bring the indicator to 50 thou in the correct direction of rotation
Write the number down
Got past max lift again to 50 thou on the other side of the lobe
Write the number down & divide by 2
This is the ICL
Move as necessary to put it where you wish
