"But the bottom cyl part of the gasket on the inner surface is badly damaged."…..Do you mean that the cylinder deck sealing surface under the blown head gasket is damaged? I fear there is more damage as well, hopefully I’m wrong. Take some emery to the lower cylinder to remove rust/glaze to get a better look. Take a wire brush/wheel to the piston dome and inside the cylinder head as well, look for little dimples that might be from broken ring chunks banging around in the combustion chamber.
