Plug wires for HEI and stock exhaust

[jfalesi]

I've got a GM Goodwrench 350 with HEI and stock exhaust manifolds. I pulled the plug wires off a while ago and just got around to installing new ones. For some reason, I had purchased these, which do not appear to be correct for my truck. There's at least one wire that's way too short. I did some searching it sounds like Taylor is pretty popular. I believe this is the correct set ('71 C10 Suburban). I also cut the wire loom brackets off of the valve covers, so I need another loom solution. I saw that GMCPauls offers some, but I was wondering which one(s) I would need. There are rear, side and oil pan mounted retainers. Also wondering if I need the heat shields.

Thanks!
