Plug wire recommendations

I like the Bosch ones from Autozone. Are they the best wires ever? No. But they are decent 8mm silicone wire-wound. More importantly, they are $30 a set with lifetime warranty, so I just get new wires every couple years. /forums/images/graemlins/thumb.gif
I also always carry a couple of spare wires with me in case something happens.

I tried to find some info about the best insulated wires as far as touching the exhaust and not melting. Never found anything though. That would be some useful information. Anybody seen anything like that?

You can look on Summit or Jegs and find spark plug wire insulators. I think mainly for the boot area.
For the cost of those things, get creative with some plug wire holders from the wrecking yard.
Just as an example, Oldsmobile V8's from the 80's (Cadillac and Oldsobiles used the Olds 307) had spark plug wire holders that bolted to the valve cover bolts.
On my Vortec heads (unsure on older heads) there are two bolt holes that match the perimeter valve cover bolts. Heck, could be same threads as the centerbolt valve cover bolts too, never checked. Anyways, I got some bolts, bent/cut the Oldsmobile plug wire holders so the wires cleared my exhaust by as much as possible.

You can see them there, sticking out between the headers and head. I used the wire clamps GM used on the wiring harness so that I could clip the plug wire in place on three of the locations.
If you spend time on routing and retaining the plug wires solidly, there is no reason to need insulation. That is why GM routed their wires down the back of the block and from below up to the plugs when the manifolds were over the plugs.
