Is this statement for the new, modern day aluminum spark plug holes or is it specifically for our flatties? I think it’s for more modern day stuff ( a CYA-statement perhaps?). If you have used anti-seize all this time and without any negative effects, I would continue to do so. We would need a lot more data to draw any specific conclusions for stock or aftermarket lumi heads, old or new, driving conditions, how far you go, and whatever other variables you come up with ....
