Blueprints for head gaskets

Good Morning! I'm trying to locate blueprints specifically for head gaskets for primarily small block chevrolet engines. If anyone could help me in this area it would be greatly appreciated. I would be interested in blueprints for head gaskets for any make small block engine as well. Thanks!! Good luck because I sure as heck haven't been able to locate any as of yet.

In case you're wondering why I'm trying to provide a lower cost alternative for copper head gaskets but I need to find a source for blueprints somehow.
