Check on my Wiring of the Junkyard HEI

You guys got some great info for me, thanks so much. One thing about solder, although it does increase the strength of the connection (physical), it is my understanding that is actually worsens the ability of electricity to freely flow through all of the available strands? Maybe it is non-issue.
When you guys say to heat shrink it, are you meaning I should run the heat shrink right up over onto the terminals? Or just the little red/blue sleeve? One of the terminals I am using is "heavy duty" and actually has the plastic sheath all the way on the terminal.

I was also thinking about putting 1 large heat shrink tube around the twisted pair of dizzy wires, and shrink them together into 1 cable. That might look cool?

My favorite part of the wiring project is I had to buy a pack of 25 of the mini 1/8 inch terminal for the module - dizzy connection. And I only will ever need 1 of them. Well actually 2 now, since I will have to cut off to get the heat shrink on it :)
