Hey guys. I have headers on my SB and #1 and #3 cylinders are giving me a heck of a time. They burn through the plug boot. I have these insulators over the boots, but they still burn through. Does anyone have any suggestions I can try? Perhaps wrapping the headers and using the insulators? How well does header wrap actually work? Is it a waste of money? It's a real pain. I have been lucky enough to have some spare plug boots, but they have run out. Next time I am going to have to fork out cash for a new set. When this does happen I was thinking of going with the Taylor 10.4mm set, but I still have to keep them from burning through. I would really appreciate any suggestions. Thanks guys.
