Which cylinder heads do you have?

Tapered seat plugs or the one that has the compression washer?

Well, there's no washer so tapered seat I guess? Thank you for the article, very informative! I think a plug change to a step or two cooler might be a cheapish experiment. Going to try non-ethanol premium on my next fill up to see if that helps as well.
