Could have been a lot worse!
no other signs of burning either looking at the fire rings & general gasket condition so just looks localized to the weakest area of that part of the gasket (between fixings) 
make sure the escaping gases have not eroded/deformed the block or head carefully 
a nitrous induced failure I presume Edited by Sardonicus on Saturday 30th August 11:56

after cleaning away the scorch marks i can barely feel anything with my nail. Guess i dodged a bullet this time. no other signs of burning either looking at the fire rings & general gasket condition so just looks localized to the weakest area of that part of the gasket (between fixings) make sure the escaping gases have not eroded/deformed the block or head carefully a nitrous induced failure I presume Edited by Sardonicus on Saturday 30th August 11:56
Yes a nitrous mistake. I have a 3rd nitrous solenoid with a very small jet that is operated by the left red button on the steering wheel. This is to weaken the mix as it goes rich off the scale on the wideband when i am full tilt in 3rd gear. Works a treat. BUT... i didnt use stage 1 (the full throttle system) and hit the left button with stage 2 (the right button). So it may have gone a weak towards for a moment!
no permanent damage 
I wouldn't be surprised if you had a shard of metal that has got jammed against the fire ring, then heated up & melted the ring....
You can see scores at the top of the bore & the piston ringland looks from the picture to have lots of rubbish around it. (meticulous cleanliness essential).

Yes, I am learning much more about nitrous recently and the thing every one keeps telling me is be very careful not to run lean. It would be great to catch up with you at some point as you clearly know much more about nitrous than I do and I could pick your brains on a few questions.Yes a nitrous mistake.

Mine runs off a progressive controller which comes in at 40% and ramps up to 100% over 2 seconds which is triggered by a throttle switch so no buttons to press so hopefully I won't be able to make any mistakes...hopefully.

Why not Turbo it ? then add Nitrous if you dare .
