Gentlemen,
Yes I did get some solid copper head gaskets cut a few years ago. There are a couple of things that I changed on the drawing as a result of that exercise.
In the attached photo you can see that I have allowed more material in the area at the side of combustion chambers and also the holes with the red arrows have been reduced in size.
Attached is a print of the drawing as it currently is, this was drawn off the High Compression gasket, however I also did a drawing for the Low Compression gasket.
The gaskets that I had cut for Colin have no water holes as he is building a dry decked engine as Ian pointed out so there are no water holes at all in his gasket.
The point about solid copper gaskets is that they need to be annealed before fitting, and also on the A7 engine with the small diameter head studs there is a limit to what torque you can achieve on the head studs.
Cheers
Marcus
