I just bought a Cometic head gasket 84mm .051 thickness and I was wanting to know if you can spray a copper coating on the hg like you would with a golden eagle hg? Cometic says that they have a rubber like coating on both sides of the gasket but didn't know if that would be good enough for sealing purposes? thanks

I didnt use any copper spray on my .060 81.5mm gasket and it has about 6000 miles on it so far with no leaks, or overheating problems.

Copper spray ftw mang! Added insurance and costs what,5.00? (sure as heel doesn't hurt anything,and I've used it since the 80'z...)

any body else have any insight to this? I plan to make close to 500hp.

Use it for extra reinsurance, it can't hurt.

I work at a Honda dealer and I have put on copper spray on all headgaskets since 1990 (metal) and I used it on my boosted integra and I have over 60K on it.

We use hylomar blue spay on the cometics

Thank you. Since cometics have a special coating now I didn't know if it would affect it. Where do you pick up the hylomar up at?

We get it from Hylomar themselves. You get the manifold and new turbo put on yet?

no I had a blown headgasket, hopefully that's all it was. Took the head of to get checked and came back good with vaccum and surface. But they noticed that it looked like the piston was hitting the head, possible too much taken off of the block. That's why I got this gasket. Tomarrow I'm taking my head back to the head place to have them open up the chamber to 84mm and to deshroud the valves a little bit. Hopefully these things will help with the problems I was previously having. I'm waiting on the injector dynamics injectors to show up. So it should hopefully be up and running by next week. Also sold my used slicks and getting new ones. Just have to light a fire under someones *** to get moving on getting parts in. lol

Which one do you get from them? the advanced one?
