How Painless is it second time around

So i get a clear idea of how the factory had it.
then see how painless wants it and see if I can get er done!
I'm starting at engine distributor and will work my way back.
Once I'm familiar I will add the newer tech Mallory dizzy , MSD 6a and such
My hope would be someone has diagram or chart for the DART? kit
I found some documentation on Painless website but even then its better to hear from someone who has been there.
thanks again
