I would have to agree. There's no gain, other than to get back what was lost due to a damaged head.

If you'd like to see some of the damage that can be done, look at my pictures, below, in the Trooper 2.6 section. The original head had cracks and burned valves. I couldn't keep a head gasket in it more than about a year. To the best of my knowledge that engine never overheated.
