Well, My cheapo old headers were too close to one plug/wire boot and burned through, started arcing, missing, etc etc. I replaced the wire, and made my own heat shield. Here's what I did:
Cut up a Diet Coke can
Cut up an oven mitt (temp coated part)
Made a sandwich
aluminum
material
aluminum
and pinched up the 3 edges into seams
I then wedged in b/t the header pipe and spark plug boot (smooth edge first) and VOILA! Now I better go get a fire extinguisher to carry with me, just in case.
I'll get a pic soon.
