Them plugs dont look bad at all tbh. The electrodes have been a bit damaged suggesting its not been running right. Your initial issue is going to be a fuel mixture issue but we can deal with that once you've found the issue with the high revs.
Its not a HG mate. As others have said, there is a resonator on the bottom of the inlet manifold. When these backfire it can blow the join apart on that resonator meaning there is unmetered air getting in hence your bouncing from the red line.
Take the manifold off and have a look at the resonator. Id put money on that being fooked.
These GTI engines dont blow head gaskets that often at all but if they did it would be the same symptoms of any HG failure. Loss/mixing of coolant/oil, pressurised coolant system, over heating etc etc.
