MSD distributor tuning

How high? And what springs were in it when you did it?
One silver heavy, and one silver light. Revved it well above anything that I would ever be driving it. I dont have a tach, but it was screaming. Guessing well over 3000. My dial back timing light never went past 30*
I think I need to go to the light saver and blue springs and hope the timing gets closer to 36*
