Pinging at higher rpm

Ok
I am running 91 for gas
I will play with the mixtures
I think I need to adjust the timing at idle
I assume if I want total timing around 36 I should do that adjustment when the springs I have in have all the timing in it for example if all the advance was in at 2000 I should time it to 36 at 2000 rpm right?

whatever rpm the mech advance tops out at.

35-36* should be all you need
