Copper anti seize and Aluminum heads

I use the copper.
Use copper anti seize, we use it at my work, and I have used it a lot on some used car sale cars at my work, no problems to report.

I use anti seize where its stated to use it. That and no problems listening to my father and grandfather on its uses. Opinions vary though.

There have been extensive discussions and debate on this subject but virtually all plugs are already have a special anti-seize coating plated on them.

Yet some people still report stripping threads where plugs have seized in the holes.
Copper is what I use and I think Nickle is used for HT exhaust type components. You might want to check the Never Seize site.
With moisture, corrosion can occur.
Of course anti seize is not pure copper - maybe it is safe.
A chemistry teacher I once had admitted to using brass rivets in his home made aluminum canoe - they were pretty, but he did not like things coming apart once it was exposed to water!
Galvanic action!

Well I emailed Permatex with this question. They gave a very short reply which went something like this:
Thank you for your interest. We make a copper anti sieze. Click here .
Im back and forth on the anti seize. This second Im saying no anti seize. Was just wondering if it would be safe next to aluminum.

That has been fixed for the last 5-6 model year engines.

I've been specialised in servicing aluminium head engines for 2 decades, and never for once would I have to resort to use any antiseize of any kind so far.
2 things to observe:
1. always follow factory torque specifications and torque it dry (or "as-is", straight from the factory package). No additional lubricants of any kind should be added to the threads.
2. always form a habit of undoing the spark plugs every 2 yrs or so and then wirebrush the threads (then retorque them) even though you are certain that the spark plugs electrodes are in ship shape. This will keep the spark plug holes and threads free from dirt and deposits that binds.
My 2c's worth.

The thing is, plug and cylinder head threads can be dry or wet [used]
So there are very real elements of variation there no matter what.
I like a TINY bit of AS smeared on the threads of the plug - the normal silver kind.
Stuck plugs are a very real problem . Cars that have not been serviced for a long time often have problems.

I have the silver permatex anti seize. I've been wanting to try the copper when my ounce tube runs out but have yet to find any. All I saw at oreilleys was the small packets and at AAP they only carry the silver. Where to find without going online?
Don't use antiseize on sparkplugs.
From AC Delco:

Do not use any type of anti-seize compound on spark plug threads. Doing this will decrease the amount of friction between the threads. The result of the lowered friction is that when the spark plug is torqued to the proper specification, the spark plug is turned too far into the cylinder head. This increases the likelihood of pulling or stripping the threads in the cylinder head. Over-tightening of a spark plug can cause stretching of the spark plug shell and could allow blowby to pass through the gasket seal between the shell and insulator. Over-tightening also results in extremely difficult removal.
From Autolite:

We do not recommend the use of any anti seize products for installing spark plugs. Antiseize compounds are typically composed of metallic, electrically conductive ingredients. If antiseize compounds come in contact with the core nose of the plugs, it can lead to a misfire condition. Antiseize compounds can also have a torque multiplying effect when installing plugs. This can lead to thread distortion and thread galling resulting in cylinder head damage. Autolite spark plugs are nickel plated to resist the effects of corrosion and seizing. However, plug seizure is aggravated further when steel plugs are installed into aluminum cylinder heads for a long period of time. You may want to consider the periodic inspection of the plugs to reduce the likelihood of plug seizure during extended plug service intervals.

The use of anti-seize on spark plugs is only recommended on those brands that
do not offer a special metal shell plating. Spark plugs that have a shiny silver
appearance on the metal body usually indicate that the spark plug is
manufactured with special metal shell plating.

Champion recommends that you do not use an anti-seize compound, since one has already been applied to the plugs at the factory.
