Poll what type of head gasket sealant do you use

Since they’re so many professional mechanics on this form, I thought I would ask this question just for fun to see what is used.

What type of Head gasket sealer do you use when you work on a Head?
 

[Case Nutty 1660]

when I do which is not very often and only if I see a reason too I use Permatex Copper Coat
 

[JW]

None.
 

[Adirondack case guy]

None!! you get a false torque in the headbolts.

None and lots of it. Actually I have used the spray-on copper coat on one lungers when I just pop the head to take a peek and reuse the gasket.

I use copper coat especially on the smaller 4 lungers where the push rod tube area likes to leak.
 

[830 man]

None ever.

I use some copper silicone around the pushrod galleys on a C-D-L, they have poor clamping on that side and will weep oil, otherwise usually nothing, a little copper coat is ok if there is fears of the water passages not sealing, some use aluminum spray paint, hylomar is another product

Hylamar, Copper coat, or Indian Head gasket sealer. Depends of why I am using it. I have never seen a head walk on a block if sealer is used. I have taken engines appart where no sealer was used and the head gaskets were warn 1/16" into the block. If they start moving they can make a big mess in a hurry.

Nothing, ever, read the book, I have never seen sealer recommended.
