I have tried this on a very tired engine. It may have helped but I duno. To get carbon off the valves I have hit the rockers on the valve side to knock them around a bit with a heavy rubber mallet. Made a noticeable increase in compression when doing leak-down type tests.

Learn from the mistakes of others, that way when you mess up you can do so in new and interesting ways.

One mile of road will take you one mile, one mile of runway can take you around the world.
