Aluminum head anti seize

[russcc]

What is the recommended anti seize for the head stud shoulders within the head to prevent the corrosion between the steel stud and the aluminum head, I understand that aviation grade anti seize is the best for this application. What is the base of the anti seize, copper, nickel, graphite ?
Thank you Fordbarn.

Thank you fordbarners. I found that there are 2 types of aviation type anti-seize. 1 is for steel spark plug threads into an aluminum head, and the other is a zinc & petrolatum anti-seize that is general purpose, and what I was looking for. Will post my findings for future reference.

I cannot state that this works because I have not had to remove a head, but it is what I've done with my heads, cast iron and aluminum, on two engines.

To me it is intuitive, if you keep the bolts or studs centered in their holes, then there should be little corrosion or electrolysis that impairs head removal. I also used anti-seize on the shanks as added insurance. Be aware, you have to buy a special bit to drill the heads to accept the washers.
