Copper Head Gaskets
Anyone use these on a street engine? I am considering using them to reduce compression when I swap on a set of small CC chamber heads.

It's tough to get them to seal the water passages well on a street motor.Possibly with some Hylomar sealant.If you want thin, use a steel shim type gasket.These are embossed around the water passages and are also very thin when compressed.I'm using these on my big block.
If you are trying to decrease compression, I think the aftermarket composition gaskets will be thicker when compressed than the copper.

Which type of composition gaskets? The deal is that this is my 406 so I am going to have to drill steam holes, unless I can get a really good 400 sbc gasket.
I take it you have heard about the same sealing issues? I have heard that Hylomar is a pretty good sealant though.

You can use steel shim gaskets and some copper spray gasket stuff. That's what I'm using on my 305.
