Swapped in my rockers and ls6 springs today and got a bit worried after pulling my plugs out. All 6 have a reddish tint on the porcelain And some white specks on them. My first thought was burning coolant, but there is nothing in the oil and because I was paranoid I did a leak down test on all cylinders and all showed between 5-6% leakage which leads me to believe its not head gaskets. What do you guys think? Right now they are stock heat range, unknown miles on them ( had the car for about 15k miles) and the only mods up till today are SD headers, everything else is bone stock. Let me know what you think.
