Reply To: Anti-Seize for Gasket Sealer on Head Gaskets?

[Don]

I usually don’t recommend using the “anti seize” due to possible electrolysis issues. But, I see the product you are using is meant for aluminum, so am guessing it won’t be harmful.
That being said, the anti seize compound is not a sealer, it is a protective lubricant, so using it on the gasket surfaces offers no benefit at all. The anti seize should be used on the head bolt threads to keep them from seizing to the block. The OMC gasket sealer can be used the same way. The gasket you are using clearly says do not use sealer, it is impregnated with its own sealer. It is important to make sure both surfaces are flat, and retorque the head bolts after initial running….
So, I guess I am saying that coating those surfaces with anti seize like what I see pictured is a mistake….
