Annealing Copper Head gaskets

agggilli · Posted: Fri Apr 29, 2011 8:25 pm Post subject: Annealing Copper Head gaskets

I bought new copper head gaskets for my new build. Do I need to anneal them before I use them or is that just done only if reusing used ones. Also, I read one article that said to cool them quickly in water and another that said to cool them slowly in the air. Which is it? Question

You would let them cool slowly, but this is usually for a used item, not new.

You can use them right out of the package...and over again with the same heads/case without touching them (eg. if changing camshafts, etc, just re-install).

One of the advantages of copper head gaskets is that you may not have to use cylinder shims (or can use fewer shims), which keeps more of the cylinder down inside the case, for better piston skirt support. I've used them on my 2017 and 2332 cc engines...no head leaks ever. Probably not necessary on a stock engine, but useful on some strokers...

I use them right out of the packaging.On my case i dont need to use any shims and got .050 deck with an 82 crank and 5.4 rods so i used copper shims instead.Makes it way easier if i decide to up the compression later too.

Never used any until this build.

They are not gaskets and do not seal anything. All they are is a shim with fancy marketing scam to get your money. I have never used them on any VW engine I have ever built.

I use them right out of the package. Another plus in using them, is that you'll never see the sealing surface of the head get Hammered from the cylinder digging into it.
I really don't understand why anyone would be hating on them.
What problems do they cause?
What Damage do they cause?
I've not seen any downfall to using them.

I've seen two motors now die because of those pesky head gaskets.
I couldn't agree more with Joe. Throw them things as far as you can, then run the other direction! Laughing

I don't like stacking base shims, so using a head gasket is nice to get the deck where you want it without stacking base shims/spacers.

hmm but..well hmm .hmm,butt....hmm,ah hmm but they do seal !!!if they dont it wouldnt of sealed with out them.and they do help transfer heat from the cyl where there is no fins to the head witch suckes up the heat to be blown away. and yes they are a shim.and a gasket. just like the head shims for chevy& dodge.they are also a gasket.why did vw not use them??IDK.but they were not real woried about water leaking, and the awassom power of the oe motors why bother??I ahve pulled appart motors that had the chambers machined over .005"out side to side and they sealed, that is 1 cyl down over .005 in the center and the other cylinder up and down on to ex side.and they sealed just fine,(somebody did not tram in thier mill or something) I dont think it would or sealed at all with out them. use them or not. I do.
