What would you use this for?

I was going through my stuff and I found a Copper 4g32 head gasket shim. What would you use this for? Sandwiching 2 head gaskets to decomp an engine? Its much less than 1mm thick..

sounds like a head gasket to me I use to run a 0.020" copper head gasket on a 2Lt astron ( about 0.5 mm ) that not an uncommon size

Much less tollerance of head warp then im guessing? Or is there enough flex in the head to ensure A snug seating?

well if you are using a coper head gasket you do need both head and block to be true - I at the time couldn't get a 2 lt astron head gasket only 2.6 parts
of cause they would seal the head but with a large area outside the combution chamber for fuel/air mix to hide - this made no sence to me with the amound of work done to improve power

I had no problems with the copper gasket and of cause you can keep reusing them - to aneal them ( make them soft again ) just hear to gasket up till it starts to turn colour and let it cool
