I just installed expensive(to me at least) ceramic coated headers on my '69 Super Bee with 383. The #6 plug wire boot is super close to the header tube, burns in a small amount of time and shorts out. I've used an insulated sleeve and it eventually allows the boot to burn away too. I don't want to bend and beat on the headers and mess up the coating. I'm using MSD high heat wires/boots. Any suggestions...?
