Im a little unclear on what you are saying,,, Are the boots or wires melting? If its the wires, your only choice is to route and hang them so they dont touch. I have run every make of wires out there, and if they touch, they will melt, even with boots
If its the boots, get the accel ceramic boots: They will do the trick, I run them, and they are the only thing that works. As you found out, socks dont work, they didnt for me either.
As for the angle, you'll have to decide on that. Typically though, 90 degree boots will get you the clearance you need on all cylinders.
