Ebay copper head gasket??

[OlderThanMe]

Here is a copper head gasket that is available in 1mm and 2mm thicknesses. I haven't seen this kind of HG for sale before. Is there an advantage of using copper over an HKS style metal head gasket?

How many times can a copper head gasket be torqued? Soft copper deforms fairly easily so that makes me think it can be used once or twice.

Price is $186...eh.

How would this do on a high compression or turbo L6?

well copper head gaskets for the most part weep coolant and oil and require O rings on the cylinders to seal well, most run some radiator stop leak to help or stop the coolant weeping but oil will almost always weep out.

the copper HG is a good way to go if you are building an all out race engine. I have checked in to these HG's and found that they are not practical for a street engine and to stick with a stock or comparable HG. My info came from the manufacturers, and people i know in the area who race and tear their engines down after each pass

I knew a guy who used a copper HG on his BSA motorcycle. He was having trouble with it because I think the head wasn't flat (been a few years, but I'm pretty sure that was the problem) so it kept leaking at the headgasket. He would clean it and then re-anneal it, which was basically getting it really hot with a MAPP gas torch, and reinstall it. Once he finally got the surfaces machined flat he didn't have any more problems. I think I'd rather go with the HKS style if you wanted a metal headgasket, but the copper does work.
