I have installed an aluminum "Rocket" head from Secrets of Speed on my Model A. I wonder about using this: https://www.amazon.com/Jet-Lube-Anti.../dp/B009VO2O1Y

What does everyone think about using anti-seize on spark plug threads?

Thank you in advance.

I always use some anti seize on sparkplug threads going into aluminum heads, just don't overdo it. The plugs still need to ground to the head.

Guten Abend Paul.

Never use copper paste with aluminnium.

Use white ceramic grease. (It is also available for aircraft engines as heat-conducting paste.)

Get regular spark plug anti seize at your local parts store. All new car have aluminum heads and use it. Check the torque specs don't overdo it.

Gents -

After considering the advice, especially the part about not using anything with copper in it between steel and aluminum threads, this is what I ordered: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Thanks to all.

It will work fine. I use a comparable product made by Permatex, but it's the same stuff.

I once tried using aluminum anti-sieze on spark plugs in a cast iron head, never again. After 3 or 5000 miles, removing the plugs was a chore, the anti-sieze had turned into a tough paste, almost like the plugs were glued in.

I used copper base antiseize but changed over to nickel based for stainless fasteners on the turbine engines. Either is fine for model A engine fasteners. Any antiseize should work on them since there are no original stainless fasteners in the early Ford cars.
