reading the slant six plugs color

Thank you Kosmic..............is it visually obvious which is lighter or do you have to tug on them
to tell? more or less loops in one vs other?
And if I look in there and see two identical looking springs because I made the error of putting in identical springs , can you tell me the location of the heavier one ? Like is it closer to the points? Dfferent mounting tag?

Yes get the fbo plate and take timing out of your distributor set it at 18 limit slot put in the mr gasket light spring leave in the original lighter spring that came with the dizzy. Add more initial timing and lower your curb idle adjust mixture and go. Your problem is higher compression with late timing equals a lot of curb idle which equals to run on aka dieseling. You will feel a hell of a difference.
