You will run waay hot with that timing^^ if running points
Better to run less timing for break in period. If you can keep the head temp under 400 degrees 18+ degrees works great for those reed kits.
If you run a ignition with a curve then hi timing works good
I just look at it like this if you have to ask then you not familiar with this stuff so low timing and you will be safe .
Set points 17-20 thousand before you set timing if running points
