The nitrite coating. I have before and was told by cometic to use some warm soapy water to I guess temporarily loosen some of the nitrite around that area and you can move the nitrite around with your fingers to fill in any gaps. I use copper spray on my cometics mainly just because in my mind it made more sense. Correct me if I'm wrong because this is strictly theory, but what do you think the chances would be of the nitrite and cooper spray gasket warming up on first strart and kind of mix together to provide a better seal???
What boost/power do you usually see stock headgasket and stock head bolts give out?
